LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an excellent liquid crystal display device capable of expanding a visual angle rapidly and largely and capable maintaing a satisfactory display grade without lowering display picture quality possessed by a liquid crystal cell, and which has high picture quality and a wide visual angle. SOLUTION: This liquid crystal display device is a liquid crystal display device to whose observation surface at least a microlens array sheet 61 is attached. The microlens array sheet 61 is such a array sheet that the diffusion degree at the time when a luminous flux is made incident from the normal direction of the face A of one side of the sheet, has a diffusion degree larger than that at the time when luminous flux is made incident in the normal direction of the face B opposite to the face A of the sheet and the microlens array sheet 61 is attached to the observation side of a liquid crystal cell 60 by making the face A of the array sheet 61 to be on the liquid crystal cell 60 side and the face B of the array sheet to be on the observation side.
