Abstract

A liquid crystal display includes: a substrate including a display region and a non-display region, the non-display region including a first region adjacent to the display region and a second region further from the display region than the first region; a light blocking member disposed in the non-display region of the substrate; and a plurality of step providing layers disposed between the substrate and the light blocking member in the non-display region of the substrate, the step providing layers spaced apart from each other. A height of the light blocking member disposed in the first region of the non-display region is different from a height of the light blocking member disposed in the second region of the non-display region.

Claims (35)

1. A liquid crystal display comprising:

a substrate comprising a display region and a non-display region, the non-display region comprising a first region adjacent to the display region and a second region further from the display region than the first region;

a light blocking member disposed in the non-display region of the substrate; and

a plurality of step providing layers disposed between the substrate and the light blocking member in the non-display region of the substrate, the step providing layers spaced apart from each other,

wherein a height of the light blocking member disposed in the first region of the non-display region is different from a height of the light blocking member disposed in the second region of the non-display region.

2. The liquid crystal display of claim 1 ,

wherein the height of the light blocking member disposed in the first region is smaller than the height of the light blocking member disposed in the second region by about 0.5 micrometer or more.

3. The liquid crystal display of claim 1 ,

wherein a width of the first region is equal to or greater than about 16% of a total width of the non-display region.

4. The liquid crystal display of claim 1 ,

wherein a width of the first region taken from the display region is about 800 micrometers.

5. The liquid crystal display of claim 1 ,

further comprising a color filter disposed in the display region of the substrate,

wherein the step providing layers disposed in the non-display region include a same material as the color filter disposed in the display region.

6. The liquid crystal display of claim 5 ,

wherein

the color filter disposed in the display region of the substrate comprises a blue color filter, and

the step providing layers disposed in the non-display region comprise a same material as the blue color filter.

7. The liquid crystal display of claim 6 ,

wherein the step providing layers disposed in the non-display region comprise a first step providing layer disposed in the first region, and

the first step providing layer disposed in the first region is elongated in a length direction of the first region.

8. The liquid crystal display of claim 7 ,

wherein in a width direction of the first region, the first step providing layer comprises protrusions and depressions alternately arranged.

9. The liquid crystal display of claim 7 ,

further comprising a light leakage preventing layer between the first step providing layer disposed in the first region and the substrate,

wherein in a width direction of the first region, the light leakage preventing layer comprises a plurality of portions spaced apart from each other.

10. The liquid crystal display of claim 9 ,

wherein the light leakage preventing layer comprises a metal slit pattern.

11. The liquid crystal display of claim 10 ,

wherein in the width direction of the first region, an interval between adjacent patterns of the metal slit pattern is equal to or less than about 5 micrometers.

12. The liquid crystal display of claim 5 ,

further comprising a gate insulating layer disposed in the non-display region of the substrate,

wherein

the step providing layers spaced apart from each other in the first region are defined by protrusions of a unitary step providing member in the first region of the substrate, and

the second region of the non-display region excludes the step providing layers.
