摘要： In a liquid crystal display element particularly that having a mode wherein the display operation is performed by controlling the amount of birefringence of the liquid crystal layer, such as an OCB type liquid crystal display element, the contrast is improved. This is achieved by the following: the reflection of light that occurs inside the element is reduced, the reflected light resulting from the difference in the refractive indices between materials for the boundary surfaces of the portions inside the element is reduced, and the internal light, such as light from the backlight, is directed toward the direction orthogonal to the surfaces of the substrates. More specifically, a light absorbing material may be used in portions of a black matrix, active elements, and wirings formed on at least one of the substrates.
