Abstract:
1. A liquid crystal panel, comprising: a liquid crystal cell comprising 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; a half wave plate arranged between the first polarizer and the liquid crystal cell; and wherein 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 degrees; wherein the liquid crystal panel further comprises two bi-axial compensation films arranged respectively between the first polarizer and the liquid crystal cell and between the half wave plate and the liquid crystal cell; and wherein when the angle between the slow axis of the bi-axial compensation film and the absorbing axis of the polarizer on the same side is 90 degree, a central point brightness decreases and then increases in accordance with the increase of the compensation value at a predetermined wavelength.
