Abstract

Provided are a touch screen-embedded liquid crystal display panel and a method of manufacturing the same in accordance with one or more embodiments. The touch screen-embedded liquid crystal display panel may include, for example, a transparent first substrate; a second substrate which faces the first substrate; a conductive spacer and a cell-gap spacer which are formed on the first substrate; and a common electrode which is formed on the second substrate and has an aperture in a region that contacts the cell-gap spacer on the first substrate.

Claims

1. A display panel comprising:

a transparent first substrate;

a second substrate which faces the first substrate;

a conductive spacer and a cell-gap spacer which are formed on the first substrate; and

a common electrode which is formed on the second substrate and has an aperture, wherein the cell-gap spacer contacts the second substrate through the aperture.

2. The display panel of claim 1, wherein the conductive spacer and the cell-gap spacer are formed on the same layer.

3. The display panel of claim 2, wherein the first substrate comprises a first structure on which the conductive spacer and the cell-gap spacer are formed.

4. The display panel of claim 3, wherein the second substrate comprises a second structure on which the common electrode is formed.

5. The display panel of claim 4, wherein the first structure comprises a thin-film transistor (TFT), first and second sensing lines, and an insulating film which is formed on the TFT and the first and second sensing lines.

6. The display panel of claim 5, wherein a sensing electrode is formed on the conductive spacer and is connected to the first and second sensing lines by contact holes which are formed in the insulating film.

7. The display panel of claim 5, wherein the second structure comprises a black matrix, color filters formed on the black matrix, and the common electrode formed on the color filters.

8. The display panel of claim 3, wherein the first structure comprises a TFT, first and second sensing lines, and color filters which are formed on the TFT and the first and second sensing lines.

9. The display panel of claim 8, wherein a sensing electrode is formed on the conductive spacer and is connected to the first and second sensing lines by contact holes which are formed in the color filters.

10. The display panel of claim 8, wherein the color filters comprise a red filter, a green filter, and a blue filter which have different thicknesses.

11. The display panel of claim 10, wherein the cell-gap spacer is formed on a thickest color filter from among the color filters, and the conductive spacer is formed on a color filter of a different color than the color filter on which the cell-gap spacer is formed.
