Abstract

A liquid crystal display device includes: a first substrate including a first light blocking region, wherein a plurality of transistors are formed in the first light blocking region; a second substrate facing the first substrate, the second substrate including a common electrode disposed thereon; and a liquid crystal layer interposed between the first substrate and the second substrate, wherein the first substrate includes: a data line disposed extending in a vertical direction; color filters, each of the color filters overlapping adjacent color filters to form a color filter overlapping portion in boundary regions of the color filters in a vertical direction; and a light blocking member disposed extending in a horizontal direction covering the first light blocking region, wherein the data line and the color filter overlapping portion are spaced apart from each other in a horizontal direction in a region where the light blocking member is formed.

Claims (21)

1. A liquid crystal display device, comprising:

a first substrate comprising a first light blocking region, wherein a plurality of transistors are formed in the first light blocking region;

a second substrate facing the first substrate, the second substrate comprising a common electrode disposed thereon; and

a liquid crystal layer interposed between the first substrate and the second substrate, wherein the first substrate comprises:

a data line disposed extending in a vertical direction;

color filters, each of the color filters overlapping adjacent color filters to form a color filter overlapping portion in boundary regions of the color filters in the vertical direction; and

a light blocking member disposed extending in a horizontal direction covering the first light blocking region,

wherein the data line and the color filter overlapping portion are spaced apart from each other in the horizontal direction in a region where the light blocking member is formed, and

wherein the light blocking member comprises an opening in the vertical direction in a region where the light blocking member crosses the color filter overlapping portion.

2. The liquid crystal display device of claim 1 , wherein the first substrate further comprises a shielding electrode disposed extending in the vertical direction to form a second light blocking region.

3. The liquid crystal display device of claim 2 , wherein the shielding electrode is interposed between the data line and the common electrode.

4. The liquid crystal display device of claim 3 , wherein:

the shielding electrode comprises an extension portion corresponding to the region where the opening is formed.

5. The liquid crystal display device of claim 4 , further comprising:

a first spacer disposed on the light blocking member, the first spacer supporting the first substrate and the second substrate; and

a second spacer disposed on the light blocking member, the second spacer having a lower height than that of the first spacer,

wherein an overall height of the first substrate comprising the light blocking member is lower than a height of the second spacer.

6. The liquid crystal display device of claim 5 , wherein the first spacer, the second spacer, and the light blocking member are formed of the same material.

7. The liquid crystal display device of claim 1 , wherein the data line and the color filter overlapping portion overlap each other in a region where the opening is formed.

8. The liquid crystal display device of claim 7 , wherein the data line is curved in the region where the opening is formed.

9. The liquid crystal display device of claim 8 , wherein the data line comprises a spacer portion in a region where the light blocking member is formed and the opening is not formed.
