Abstract
A liquid crystal display unit has: a pair of opposing substrates; an electrode pattern formed on each of the substrates on an opposing surface side; a vertical alignment film formed on each of the substrates and covering the electrode pattern; a liquid crystal layer squeezed between the substrates; and a pair of polarizer plates formed on the substrates on an opposite side to the side of said liquid crystal layer, wherein an edge of the electrode pattern includes a zigzag pattern parallel to one of axis directions of the polarizer plates and a direction perpendicular the axis direction. Optical through can be reduced along an edge portion of a pixel of a vertical alignment LCD.
Claims7
A liquid crystal display unit comprising:
- a first substrate and a second substrate opposing each other;
- a first electrode pattern formed on said first substrate;
- a second electrode pattern formed on said second substrate;
- a vertical alignment film formed on at least one of said first and second substrates and covering at least one of said first and second electrode patterns;
- a liquid crystal layer sandwiched between said first and second substrates;
- and
- a pair of polarizer plates disposed outside said first and second substrates and having crossed-Nicols;
- wherein:
- an edge of at least one of said first and second electrode patterns includes a sawtooth pattern comprising a plurality of serially connected teeth with edges of the teeth being parallel and perpendicular to one of said crossed-Nicols;
- one of said first and second electrode patterns includes a segment electrode;
- the other of said first and second electrode patterns includes a common electrode;
- an overlapping area of said segment electrode and said common electrode defines a pixel;
- and
- said pixel is defined by a first pair of parallel sides and a second pair of parallel sides, and each of said first and second parallel sides is parallel or perpendicular to one of said crossed-Nicols.
