Abstract

A transverse electric field type liquid crystal display panel includes a pair of substrates opposed with a liquid crystal layer interposed therebetween. A plurality of sub-pixels having at least one curved portion in a display area are provided in a matrix on one side of the pair of substrates, and a pair of electrodes having at least one curved portion are formed in the plurality of sub-pixels. A light shield layer shielding a non-display area positioned on an outer peripheral side of the display area and between the plurality of sub-pixels is formed on the other side of the pair of substrates. The light shield layer of the non-display area is formed in a shape in which the outermost peripheral side of the display area is rectangular.

Claims (11)

1. A transverse electric field type liquid crystal display panel comprising a pair of substrates opposed with a liquid crystal layer interposed therebetween,

wherein a plurality of sub-pixels having at least one curved portion in a display area are provided in a matrix on one side of the pair of substrates, and a pair of electrodes having at least one curved portion are formed in the plurality of sub-pixels,

wherein a light shield layer shielding a non-display area positioned on an outer peripheral side of the display area and between the plurality of sub-pixels is formed on another side of the pair of substrates, and

wherein the light shield layer of the non-display area is formed in a shape in which the outermost peripheral side of the display area is rectangular.

2. The liquid crystal display panel according to claim 1 , wherein signal lines and scanning lines are formed on the one side of the pair of substrates, and the signal lines and the scanning lines are curved along the shape of the sub-pixels.

3. The liquid crystal display panel according to claim 2 , wherein when the outermost side of the sub-pixel positioned on the outermost peripheral side of the display area is an inner angle side, the light shield layer of the non-display area is formed to pass through a curved point of the inner angle side of the sub-pixel.

4. The liquid crystal display panel according to claim 2 , wherein when the outermost side of the sub-pixel positioned on the outermost peripheral side of the display area is an outer angle side, the light shield layer of the non-display area is formed to pass through an end point of the outer angle side of the sub-pixel.

5. The liquid crystal display panel according to claim 1 , wherein the sub-pixels of the outermost peripheral side of the display area have an area wider than that of the other sub-pixels.

6. The liquid crystal display panel according to claim 1 , wherein a dummy pixel is formed on the outside of the display area, and the dummy pixel is in an inactive state.

7. The liquid crystal display panel according to claim 1 , wherein the pair of electrodes are formed of a lower electrode, an insulating film formed on the lower electrode, and an upper electrode formed on the insulating film and provided with a slit-shaped aperture curved along the shape of the sub-pixel.

8. The liquid crystal display panel according to claim 1 , wherein the pair of electrodes are opposed to each other in a pectinate shape, and are curved along the shape of the sub-pixel.
