Liquid crystal display panel, liquid crystal display device and manufacturing method of liquid crystal display panel

Abstract

This object aims to provide a direct viewing type and VA type liquid crystal display panel with a microlens array that is less in display unevenness, good in viewing angle characteristic, and capable of carrying out a high brightness display. The liquid crystal display panel is provided with a liquid crystal panel (12) comprised of a light incident side substrate (30) and a light projection side substrate (32) that face each other so as to hold a liquid crystal layer (34) of vertical alignment type (VA) therebetween, a microlens array (14) having a plurality of microlens (14a) arranged on the light projection side of the light projection side substrate, an optical film (22) including a first polarizer (26) arranged on the light projection side of the microlens array, and an optical film (23) including a second polarizer (28) arranged on the light incident side of the light incident side substrate. This invention is suitable for a direct viewing type liquid crystal display device and, in particular, for a liquid crystal display device used for a mobile or notebook-sized personal computer.

Description

technical field [0001] The present invention relates to a liquid crystal display panel and a liquid crystal display device, in particular to a liquid crystal display panel and a liquid crystal display device including a microlens array. Background technique [0002] In recent years, liquid crystal display devices have been widely used as display devices such as monitors, projectors, portable information terminals, and cellular phones. Generally, a liquid crystal display device changes the transmittance (or reflectance) of the liquid crystal display panel according to a drive signal, and modulates the intensity of light from a light source irradiated on the liquid crystal display panel to display images and characters. Among liquid crystal display devices, there are direct-view display devices for directly observing images displayed on a liquid crystal display panel, and projection display devices (projectors) for enlarging and projecting images displayed on a display panel o...

AI Technical Summary

Problems solved by technology

Therefore, the transflective liquid crystal display device has the advantage of being able to realize a high-contrast display regardless of the surrounding brightness, but there is a problem that the brightness decreases due to the decrease in the aperture ratio in the transmissive region.
