Abstract

A liquid crystal display device includes: a first substrate including a first light blocking region where a plurality of transistors are formed and a second light blocking region where a data line is extended in a vertical direction; a first color filter and a second color filter formed on the first substrate; a second substrate facing the first substrate and having a common electrode formed thereon; and a liquid crystal layer interposed between the first and second substrates, wherein the first and second color filters are spaced apart from each other in an intersection region of the first and second light blocking regions and are overlapped with each other in the second light blocking region other than the intersection region to form a color filter overlapped part in the vertical direction.

First claim

What is claimed is:

1. A liquid crystal display device comprising:
a first substrate including a first light blocking region where a plurality of transistors are formed and a second light blocking region where a data line is extended in a vertical direction;
a first color filter and a second color filter formed on the first substrate;
a second substrate facing the first substrate and having a common electrode formed thereon; and
a liquid crystal layer interposed between the first and second substrates,
wherein the first and second color filters are spaced apart from each other in an intersection region of the first and second light blocking regions and are overlapped with each other in the second light blocking region other than the intersection region to form a color filter overlapped part in the vertical direction.

2. The liquid crystal display device of claim 1 , wherein:
the first substrate further includes a light blocking member extended in a horizontal direction so as to cover the first light blocking region.

3. The liquid crystal display device of claim 2 , wherein:
the first substrate further includes a shielding electrode extended in the vertical direction so as to cover the second light blocking region.

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

5. The liquid crystal display device of claim 4 , wherein:
the shielding electrode includes an extension part in the horizontal direction in the region where the first and second color filters are spaced apart from each other.

6. The liquid crystal display device of claim 5 , wherein:
the first and second color filters each include a contact hole adjacent to the shielding electrode, and
the extension part is formed so as to cover the contact hole.

7. The liquid crystal display device of claim 6 , wherein:
the contact hole is extended from a region where the contact hole is overlapped with the extension part to boundary regions.

8. The liquid crystal display device of claim 6 , wherein:
the shielding electrode is electrically connected to the plurality of transistors through the contact hole.

9. The liquid crystal display device of claim 2 , further comprising:
a first spacer supporting the first and second substrate; and
a second spacer having a height lower than that of the first spacer,
wherein a height of a region of the first substrate where the light blocking member is formed is lower than a height at which the second spacer is formed.

10. The liquid crystal display device of claim 9 , wherein:
the first spacer, the second spacer, and the light blocking member are made of the same material.
