ABSTRACT:
In a liquid crystal display apparatus in which a liquid crystal domain having radially tilted orientation is formed in a pixel, high-quality reflection display with occurrence of an afterimage being suppressed is attained. The liquid crystal display apparatus of this invention includes a first substrate110a, a second substrate110band a vertically aligned liquid crystal layer120placed therebetween, and has pixels each including a first electrode111, a second electrode131and a liquid crystal layer located therebetween. The first substrate includes a reflection layer116having a concave/convex surface and an insulating layer117formed to cover the reflection layer. The first electrode111is placed on the insulating layer117and has a shape defined to exert alignment regulating force with which at least one liquid crystal domain having radially tilted orientation is formed in the liquid crystal layer in a voltage applied state. The second substrate110bhas a protrusion125protruding toward the liquid crystal layer in a region corresponding to the liquid crystal domain.
