Abstract

A liquid crystal display panel includes: a pair of substrates opposed to each other with a liquid crystal layer interposed therebetween, one of the pair of substrates including a lower electrode; an upper electrode that is formed on the surface of the lower electrode with an insulating layer interposed therebetween and that has a plurality of slit-like apertures formed for each sub pixel; and an alignment film that is formed to cover the upper electrode and the surface of the insulating layer. The plurality of slit-like apertures are divided into a first slit-like aperture group including a plurality of slit-like apertures extending in a first direction and a second slit-like aperture group including a plurality of slit-like apertures extending in a second direction different from the first direction. The angles formed with a liquid crystal alignment direction in a voltage non-applied state by the first direction and by the second direction are different.

Claims (9)

1. A liquid crystal display panel comprising:

a pair of substrates opposed to each other with a liquid crystal layer interposed therebetween, one of the pair of substrates including a lower electrode;

an upper electrode that is formed on the surface of the lower electrode with an insulating layer interposed therebetween and that has a plurality of slit-like apertures formed for each sub pixel; and

an alignment film that is formed to cover the upper electrode and the surface of the insulating layer,

wherein the plurality of slit-like apertures are divided into a first slit-like aperture group including a plurality of slit-like apertures extending in a first direction, and a second slit-like aperture group including a plurality of slit-like apertures extending in a second direction different from the first direction, and

wherein angles formed by a liquid crystal alignment direction in a voltage non-applied state by the first direction and by the second direction are different, and

wherein the absolute value of a difference between an angle formed by the first direction and the liquid crystal alignment direction in the voltage non-applied state and an angle formed by the second direction and the liquid crystal alignment direction in the voltage non-applied state is equal to or greater than 4° and less than 6°.

2. The liquid crystal display panel according to claim 1 , wherein the ends of the slit-like apertures in one of the first slit-like aperture group and the second slit-like aperture group are not connected to the ends of the slit-like apertures in the other slit-like aperture group, and the slit-like apertures are independently formed in the respective groups.

3. The liquid crystal display panel according to claim 1 , wherein the slit-like apertures of the first slit-like aperture group and the slit-like apertures of the second slit-like aperture group are connected to each other at the ends of the slit-like apertures to form a “<” shape.
