Abstract

A liquid crystal display device is disclosed. The liquid crystal display device includes a display panel that includes four sides. One of the four sides has a cut edge. The display panel includes a display region in which an image is to be displayed; a non-display region that surrounds the display region and that includes a non-light transmitting layer that restricts light transmission therethrough; and a plurality of slits disposed in the non-light transmitting layer. An edge of the non-light transmitting layer is co-planar with the cut edge. The plurality of slits are parallel to the cut edge.

Claims (13)

1. A liquid crystal display device, comprising:

a display panel having a display region, the display region including a plurality of gate lines and a plurality of drain lines;

a black matrix that overlaps the plurality of drain lines and the plurality of gate lines;

a plurality of slits formed in the black matrix; and

a plurality of pixels formed in a matrix in the display region, a pixel from the plurality of pixels being defined by two adjacent drain lines from the plurality of drain lines and two adjacent gate lines from the plurality of gate lines,

wherein the plurality of slits overlap with a thin film transistor in the display region,

wherein the black matrix includes a first black matrix, the first black matrix overlapping with the plurality of drain lines, and an edge of the first black matrix is co-planar with an edge of the display panel,

wherein each one of the plurality of drain lines is bent at a midpoint between an upper half of the pixel and an lower half of the pixel,

wherein the plurality of slits are formed at the midpoint in a direction extending along the gate lines, and

wherein the plurality of slits are covered by two adjacent color filters.

2. The liquid crystal display device according to claim 1 , wherein the black matrix includes a second black matrix, the second black matrix overlapping with the plurality of gate lines is co-planar with the display panel, and

the plurality of slits are perpendicular to the gate lines and extends along the drain lines.

3. The liquid crystal display device according to claim 1 , further comprising a substrate on which at least one color filter is formed, and part of the black matrix is disposed between the at least one color filter and the substrate.
