Liquid crystal display device
View Patent ↗A liquid crystal display device has the first substrate and the second substrate. The first substrate includes a gate line, a source line crossing the gate line, a switching element connected to the source line, a liquid crystal drive electrode connected to the switching element and having a plurality of electrodes substantially parallel to each other, and a common electrode consisting of a plurality of comb-shaped electrodes arranged substantially parallel to and alternately with the liquid crystal drive electrode. The second substrate includes color filters arranged in an array arrangement and a black matrix provided between the color filters. A spacer between the substrates contacts the first substrate in the area where the gate line, the liquid crystal drive electrode, and the common electrode are arranged in the vicinity of each other.
1. A liquid crystal display device having a first substrate, a second substrate, a spacer to give a substantially equal gap between the first substrate and the second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate,
the first substrate comprising:
a gate line;
a source line crossing the gate line with an insulation film interposed therebetween;
a switching element connected to the source line;
a liquid crystal drive electrode connected to the switching element and having a plurality of electrodes substantially parallel to each other; and
a common electrode having a plurality of electrodes arranged substantially parallel to and alternatively with the liquid crystal drive electrodes,
and
the second substrate comprising:
color filters arranged in an array arrangement; and
a light shielding layer provided between the color filters;
wherein the spacer contacts the first substrate in an alignment error area proximate where the gate line, the liquid crystal drive electrode, and the common electrode oppose each other, and
a width of the light shielding layer increases in an alignment error area proximate where the gate line, the liquid crystal electrode, and the common electrode are opposed to each other, the alignment error area being a region where light leakage occurs when displaying black, and
the spacer overlaps with the gate line and the light shielding layer in an area where the width of the light shielding layer increases.
2. A liquid crystal display device according to claim 1 , wherein the spacer is arranged above the light shielding layer.
3. A liquid crystal display device according to claim 1 , wherein the spacer is arranged above the first substrate.
4. A liquid crystal display device according to claim 1 , wherein the spacer has a column shape.
5. A liquid crystal display device according to claim 1 , wherein the liquid crystal display device operates in an In-Plane Switching mode.
