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 substrate 110a, a second substrate 110b and a vertically aligned liquid crystal layer 120 placed therebetween, and has pixels each including a first electrode 111, a second electrode 131 and a liquid crystal layer located therebetween. The first substrate includes a reflection layer 116 having a concave/convex surface and an insulating layer 117 formed to cover the reflection layer. The first electrode 111 is placed on the insulating layer 117 and 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 substrate 110b has a protrusion 125 protruding toward the liquid crystal layer in a region corresponding to the liquid crystal domain.
