Liquid crystal display device
View Patent ↗A liquid crystal display device includes a first substrate and a second substrate facing each other having a pixel region; a color filter layer on the first substrate corresponding to the pixel region; a planarization layer on the color filter layer having a groove; a common electrode on the planarization layer; a pixel electrode on the second substrate; and a liquid crystal layer between the common electrode and the pixel electrode.
1. A method of fabricating a liquid crystal display device, comprising:
forming a color filter layer on a first substrate corresponding to a pixel region;
forming a planarization layer on the color filter layer and having a groove in the pixel region;
forming a common electrode on the planarization layer;
forming a pixel electrode on a second substrate; and
attaching the first and second substrate,
wherein a liquid crystal layer is interposed between the common electrode and the pixel electrode.
2. The method according to claim 1 , wherein the planarization layer directly contacts the color filter layer.
3. The method according to claim 1 , wherein the groove has a circular shape in a horizontal plane.
4. The method according to claim 1 , wherein the groove has a semi-circular shape in a vertical cross-section.
5. The method according to claim 1 , further comprising forming a black matrix between adjacent pixel regions.
6. The method according to claim 5 , wherein the color filter layer overlaps the black matrix and has a step portion at an overlapped position.
7. The method according to claim 6 , wherein an upper surface of the planarization layer is substantially even except for an area where the groove is disposed.
8. The method according to claim 1 , further including forming gate and data lines crossing each other and a thin film transistor connected to the gate and data lines and the pixel electrode on the second substrate.
