LIQUID CRYSTAL DISPLAY DEVICE

摘要

A transmission type liquid crystal display device having a liquid crystal cell and a microlens array sheet attached to the observation surface of the liquid crystal cell, wherein the microlens array sheet has at least one diffusion axis in the plane and the direction of the diffusion axis is conformed to a direction of the liquid crystal orientation of the liquid crystal cell, and a transmission type liquid crystal display device including a liquid crystal cell, a microlens array sheet attached to the observation surface of the liquid crystal cell and a backlight source, wherein a specified relationship is provided between the directivity of light emission of the backlight source and the pitch of arrangement of display elements of the liquid crystal cell in a minute unit lens arrangement direction. This liquid crystal display device is substantially independent of view angle and has a wide visible angle and high image quality. <IMAGE>
