Abstract

A display device includes a transparent plate having a first area and a second area, a first conductive line on the second area of the transparent plate, a substrate having a third area and a fourth area on the first area of the transparent plate, a display element on the third area of the substrate, and a second conductive line on the fourth area of the substrate. The second conductive line is electrically coupled between the display element and the first conductive line, and the first and second conductive lines are on different planes.

Claims

1. A display device comprising:

a transparent plate having a first area and a peripheral area adjacent the first area;

a first conductive line coupled to the peripheral area of the transparent plate;

a substrate having an emission area and a non-emission area, the substrate coupled to the first area of the transparent plate;

at least one pixel coupled to the emission area of the substrate; and

a second conductive line coupled to the non-emission area of the substrate,

wherein the second conductive line is electrically coupled between the at least one pixel and the first conductive line,

wherein the emission area of the substrate which includes the at least one pixel overlaps the first area of the transparent plate,

wherein the non-emission area of the substrate to which the second conductive line is coupled at least partially overlaps the peripheral area of the transparent plate to which the first conductive line is coupled,

wherein the first conductive line does not overlap the at least one pixel coupled to the substrate, and wherein the transparent plate does not include a pixel opposing the emission area of the substrate.

2. The display device according to claim 1, wherein the transparent plate seals the at least one pixel.

3. The display device according to claim 1, wherein the at least one pixel includes an OLED (Organic Light Emitting Diode).

4. The display device according to claim 3, wherein the OLED is formed to include an anode, a light emitting layer and a cathode, and wherein the anode and the cathode are independently coupled to the second conductive line.

5. The display device according to claim 1, wherein the second conductive line is formed of a transparent conductive material.

6. The display device according to claim 5, wherein the transparent conductive material is selected from a group consisting of ITO, IZO, SiO₂ and ZnO.

7. The display device according to claim 4, wherein the second conductive line is formed of metal.

8. The display device according to claim 1, wherein the transparent plate is formed as a chromatic plate to change a color of light emitted from the at least one pixel.

9. The display device according to claim 1, wherein the at least one pixel emits light included in a displayed text or image.

10. The display device according to claim 1, further comprising:

a groove in the first area of the transparent plate; and

an encapsulating plate over the emission area of the substrate to cover the at least one pixel, wherein the encapsulating plate is inserted in the groove.

11. The display device according to claim 10, wherein the encapsulating plate has a smaller area than that of the substrate.

12. A terminal having a body coupled to a display device as recited in claim 1.

13. The terminal according to claim 12, wherein the transparent plate has substantially a same shape as one surface of the body of the terminal.

14. A temperature control unit having a body coupled to a display device as recited in claim 1.

15. A power unit having a body coupled to a display device as recited in claim 1.

16. The display device according to claim 1, wherein the first conductive line has a length greater than a length of the second conductive line.

17. The display device according to claim 1, wherein the first conductive line has a width less than a width of the second conductive line.
