Abstract:
A liquid crystal display device of the present invention includes in the following order from a viewing surface side a first polarizer, a first positive A plate having an in-plane retardation of 120 nm or greater and 155 nm or smaller, a positive C plate having a thickness retardation of 80 nm or greater and 100 nm or smaller, a first substrate, a second positive A plate having an in-plane retardation of 120 nm or greater and 155 nm or smaller, a horizontally aligned liquid crystal layer, a second substrate, a viewing angle compensation layer, and a second polarizer. The device further includes between the first polarizer and the first positive A plate a positive C plate having a thickness retardation of 30 nm or greater and 80 nm or smaller.
