Abstract

In a liquid crystal display device, a display panel includes a display region in which an image is to be displayed, and a non-display region formed into a frame shape surrounding the display region. The non-display region includes a first region in which the gate driver is arranged, and a second region in which the source driver is arranged. The non-display region has a non-light transmitting layer formed therein, which is configured to restrict transmission of light. The non-light transmitting layer has a first slit formed therein, which extends through the first region and the second region and passes through the non-light transmitting layer.

Claims (41)

1. A liquid crystal display device, comprising:

a display panel comprising a plurality of gate lines extending in a row direction, and a plurality of data lines extending in a column direction;

a gate driver configured to supply a gate signal to the plurality of gate lines; and

a source driver configured to supply a source signal to the plurality of source lines,

the display panel comprising a display region in which an image is to be displayed, and a non-display region formed into a frame shape surrounding the display region,

the non-display region comprising a first region in which the gate driver is arranged, and a second region in which the source driver is arranged,

the non-display region having a non-light transmitting layer formed therein, which is, configured to restrict transmission of light,

the non-light transmitting layer having a first slit formed therein, which extends through the first region and the second region and passes through the non-light transmitting layer,

wherein the non-light transmitting layer further has a second slit formed therein, which is different from the first slit, and

wherein a part of the second slit is formed along the first slit and between the first slit and the display region.

2. The liquid crystal display device according to claim 1 ,

wherein the non-display region further comprises a third region opposed to the second region across the display region, and

wherein the first slit further extends through the first region and the third region.

3. The liquid crystal display device according to claim 2 ,

wherein the non-display region further comprises a fourth region opposed to the first region across the display region, and

wherein the first slit further extends through the second region and the fourth region and through the third region and the fourth region.

4. The liquid crystal display device according to claim 1 , wherein, when the non-display region is viewed from the display region, the second slit is formed so as to cover an end portion of the first slit.

5. The liquid crystal display device according to claim 1 , wherein at least one of the first region or the second region comprises a region in which the first slit and the second slit extend in parallel with each other, and a region in which only the first slit extends.

6. A liquid crystal display device, comprising:

a display panel comprising a plurality of gate lines extending in a row direction, and a plurality of data lines extending in a column direction;

a gate driver configured to supply a gate signal to the plurality of gate lines; and

a source driver configured to supply a source signal to the plurality of source lines,

the display panel comprising a display region in which an image is to be displayed, and a non-display region formed into a frame shape surrounding the display region,

the non-display region comprising a first region in which the gate driver is arranged, and a second region in which the source driver is arranged,

the non-display region having a non-light transmitting layer formed therein, which is configured to restrict transmission of light,

the non-light transmitting layer having a first slit formed therein, which extends through the first region and the second region and passes through the non-light transmitting layer, further comprising an upper frame arranged on a front surface side of the display panel,

wherein the non-light transmitting layer comprises an overlapping region overlapping with the upper frame in plan view, and a non-overlapping region free from overlapping with the upper frame in plan view, and

wherein the first slit formed in the overlapping region has a width larger than a width of the first slit formed in the non-overlapping region.

7. A liquid crystal display device, comprising a display panel comprising a plurality of gate lines extending in a row direction, and a plurality of data lines extending in a column direction,

the display panel comprising a display region in which an image is to be displayed, and a non-display region formed into a frame shape surrounding the display region,

the non-display region having a non-light transmitting layer formed therein, which is configured to restrict transmission of light,

the non-light transmitting layer having, at least on one side of the non-display region, a first slit and a second slit formed therein, which pass through the non-light transmitting layer,

the non-display region comprising a region formed in one side of the frame shape in which the first slit and the second slit extend in parallel with each other, and a region formed in another side of the frame shape in which only the first slit extends.

8. A liquid crystal display device, comprising:

a display panel comprising a plurality of gate lines extending in a row direction, and a plurality of data lines extending in a column direction; and

an upper frame arranged on a front surface side of the display panel,

the display panel comprising a display region in which an image is to be displayed, and a non-display region formed into a frame shape surrounding the display region,

the non-display region having a non-light transmitting layer formed therein, which is configured to restrict transmission of light,

the non-display region comprising an overlapping region overlapping with the upper frame in plan view, and a non-overlapping region free from overlapping with the upper frame in plan view,

the non-light transmitting layer having a first slit formed therein, which passes through the non-light transmitting layer,

the first slit formed in the overlapping region having a width larger than a width of the first slit formed in the non-overlapping region.
