Abstract

A display device includes a first substrate; a second substrate covering the first substrate; a liquid crystal layer between the first substrate and the second substrate; a plurality of pixels on the first substrate; and a light blocking member disposed on at least one of the first substrate and the second substrate, the light blocking member disposed in a curved area and defining a display area and a non-display area. The plurality of pixels includes a first pixel outside the curved area; and a second pixel in the curved area, and a pixel electrode of the first pixel has a different shape from a shape of a pixel electrode of the second pixel.

Claims (17)

1. A display device comprising:

a first substrate;

a plurality of pixels disposed on the first substrate;

a second substrate facing the first substrate with the plurality of pixels interposed between the first substrate and the second substrate; and

a light blocking layer disposed between the first substrate and the second substrate and comprising a curved inner edge,

wherein each of the plurality of pixels comprise:

a gate line and a data line disposed on the first substrate and extending in non- parallel directions;

a color filter disposed on the first substrate and insulated from the gate line and the data line; and

a passivation layer disposed on the color filter,

wherein the passivation layer comprises:

a first passivation layer overlapping the light blocking layer and recessed from a top surface of the passivation layer to form a recess; and

a second passivation layer disposed in an area around the light blocking layer,

wherein a thickness of the first passivation layer is thinner than a thickness of the second passivation layer, and

wherein the light blocking layer is disposed to fill the recess.

2. The display device as claimed in claim 1 , wherein the color filter is absent below the first passivation layer.

3. The display device as claimed in claim 1 , wherein the light blocking layer is disposed on a same layer as a layer on which the color filter is disposed.

4. The display device as claimed in claim 1 , wherein the light blocking layer comprises at least one color filter.
