Abstract

A display apparatus includes a first substrate including a display area in which a plurality of pixels is disposed and a non-display area disposed adjacent to the display area, a second substrate which faces the first substrate, an image display layer between the first substrate and the second substrate, and a sealing member which is in the non-display area and attaches the first substrate and the second substrate. The first and second substrates have a curved surface in a first direction, and a flat surface in a second direction crossing the first direction A width of the sealing member extended in the first direction is greater than a width of the sealing member extended in the second direction.

Claims

1. A display apparatus comprising:

a first substrate comprising a display area in which a plurality of pixels is disposed, and a non-display area adjacent to the display area;

a second substrate which faces the first substrate;

an image display layer between the first substrate and the second substrate; and

a sealing member which is disposed in the non-display area and attaches the first substrate and the second substrate,

wherein

the first and second substrates are curved with respect to a first direction, and are flat in a second direction crossing the first direction, and

the sealing member comprises;

a plurality of first sealing portions extending in the first direction in which the first and second substrates are curved, adjacent to upper and lower portions of the display area, and spaced apart from upper and lower edges of the first and second substrates; and

a plurality of second sealing portions extending in the second direction in which the first and second substrates are flat, adjacent to left and right portions of the display area, and spaced apart from left and right edges of the first and second substrate,

wherein

a number of the first sealing portions is more than a number of the second sealing portions,

widths of the first sealing portions are greater than widths of the second sealing portions,

the first sealing portions are connected to the second sealing portions,

the first and second sealing portions connected to each other surround the display area, and

a first width of a single first sealing portion is about 1.2 millimeters to about 2.0 millimeters, and a second width of a single second sealing portion is about 1 millimeter.

2. The display apparatus of claim 1, wherein the first and second substrates comprise long sides extended in the first direction and short sides extended in the second direction.

3. The display apparatus of claim 1, wherein

a single one of the first sealing portions is in the non-display area adjacent to the upper portion of the display area,

a single one of the first sealing portions is in the non-display area adjacent to the lower portion of the display area,

a single one of the second sealing portions is in the non-display area adjacent to the left portion of the display area, and

a single one of the second sealing portions is in the non-display area adjacent to the right portion of the display area.

4. The display apparatus of claim 3, wherein among the first sealing portions which are spaced apart from the respective edges of the first and second substrates, the first sealing portions have a same width.

5. The display apparatus of claim 3, wherein among the first sealing portions which are spaced apart from the respective edges of the first and second substrates, the first sealing portions have different widths.

6. The display apparatus of claim 1, wherein a ratio of the first width of the single first sealing portion to the second width of the single second sealing portion is in a range of about 1.2:

1 to about 2.0;

1.

7. The display apparatus of claim 1, wherein in a top plan view of, the first sealing portions comprise:

a plurality of first sub-sealing portions in the non-display area adjacent to the upper portion of the display area and spaced apart from the respective edges of the first and second substrates; and

a single one second sub-sealing portion in the non-display area adjacent to the lower portion of the display area and spaced apart from the respective edges of the first and second substrates, and

among the first and second sub-sealing portions which are spaced apart from the respective edges of the first and second substrates, the width of the second sub-sealing portion and a sum of the widths of the first sub-sealing portions are each greater than the widths of each of the second sealing portions.

8. The display apparatus of claim 7, wherein the widths of the first sub-sealing portions are equal to the widths of the second sealing portions.

9. The display apparatus of claim 7, wherein the widths of the first sub-sealing portions are greater than the widths of the second sealing portions.

10. The display apparatus of claim 7, wherein the widths of the first sub-sealing portions are smaller than the widths of the second sealing portions.

11. The display apparatus of claim 1, wherein in a top plan view, the first sealing portions comprise:

a plurality of first sub-sealing portions in the non-display area adjacent to the upper portion of the display area and spaced apart from the respective edges of the first and second substrates; and

a plurality of second sub-sealing portions in the non-display area adjacent to the lower portion of the display area and spaced apart from the respective edges of the first and second substrates, and

among the first and second sub-sealing portions which are spaced apart from the respective edges, a sum of widths of the first sub-sealing portions and a sum of widths of the second sub-sealing portions are each greater than the widths of each of the second sealing portions.

12. The display apparatus of claim 11, wherein a number of the first sub-sealing portions is different from a number of the second sub-sealing portions.

13. The display apparatus of claim 11, wherein the widths of the first sub-sealing portions are equal to the widths of the second sub-sealing portions.

14. The display apparatus of claim 11, wherein the widths of the first sub-sealing portions are different from the widths of the second sub-sealing portions.

15. The display apparatus of claim 11, wherein the widths of the first and second sub-sealing portions are equal to the widths of the second sealing portions.

16. The display apparatus of claim 11, wherein the widths of the first and second sub-sealing portions are greater than the widths of the second sealing portions.

17. The display apparatus of claim 11, wherein the widths of the first and second sub-sealing portions are smaller than the widths of the second sealing portions.

18. The display apparatus of claim 1, wherein the image display layer is a liquid crystal layer.
