Abstract: A liquid crystal panel and a liquid crystal display are disclosed. The liquid crystal display includes a liquid crystal cell having a light incident side and a light emitting side, a first polarizer arranged on the light incident side of the liquid crystal panel, a second polarizer arranged on the light emitting side of the liquid crystal panel, and a half wave plate arranged between the first polarizer and the liquid crystal cell. An absorbing axis of the first polarizer is parallel to the absorbing axis of the second polarizer, and an angle between a slow axis of the half wave plate and the absorbing axis of the first polarizer is 45 or 135 degrees. In this way, the liquid crystal display with the two polarizers parallel to each other can be in all-black state when no voltage is applied. In addition, the contrast is greatly enhanced.
