Abstract:
1. A liquid crystal display apparatus, comprising: a liquid crystal cell in a vertical alignment mode; polarizers provided on both sides of said liquid crystal cell; quarter wavelength layers provided between said respective polarizers and said liquid crystal cell, each of said quarter wavelength layers having a retardation in an in-plane direction that is substantially set at a quarter wavelength of a wavelength of transmitted light; a phase difference layer, provided between at least one of said quarter wavelength layers and said liquid crystal cell, which has main refraction index in a normal direction nz a compensation layer, provided at least between said the polarizer and quarter wavelength layer on the side of said phase difference layer, having main refraction index in a normal direction nz wherein first and second of the phase difference layers are provided between said respective quarter wavelength layers and the liquid crystal cell, have different main refraction indexes nx wherein nx
