摘要： A liquid crystal panel of the present invention has a liquid crystal cell, a visible-side polarizer disposed on the visible surface side of the liquid crystal cell, and an antivisible-side polarizer disposed on the side opposite to the antivisible surface of the liquid crystal cell. The visible-side polarizer and the antivisible-side polarizer are disposed so that the absorption axis direction of the visible-side polarizer and the absorption axis direction of the antivisible-side polarizer will be approximately parallel to each other. A polarization rotating layer that rotates linearly polarized light by approximately 45 degrees is disposed between the visible-side polarizer and the antivisible-side polarizer.This liquid crystal panel hardly undergoes distortion and can restrain leakage of light in the peripheral part. Therefore, a liquid crystal display device incorporating the liquid crystal panel is excellent in image displaying characteristics.
