Abstract

A highly reliable liquid crystal display panel in which such a trouble as mixture of foreign material is prevented. The reliable liquid crystal display panel comprises a bonded substrate including a pair of substrates and a liquid crystal layer arranged therebetween, a microlens array provided on the light incident side of the bonded substrate, a support provided on the light incident side of thebonded substrate to surround the microlens array, and an optical film attached to the bonded substrate through the support. The support has a portion projecting farther to the outer space side than the major surface of the outer surface of the support, and a vent connecting the inner space surrounded by the support and the outer space. The opening of the vent on the outer space side is formed in the projection.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, in particular to a liquid crystal display panel and a liquid crystal display device provided with 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 mobile phones. In a liquid crystal display device, generally, the transmittance (or reflectance) of the liquid crystal display panel is changed by a driving signal, and the intensity of light from a light source irradiated on the liquid crystal display panel is modulated to display images and characters. Among liquid crystal display devices, there are direct-view display devices that directly observe images displayed on a liquid crystal display panel, and projection display devices (projectors) that enlarge and project images displayed on a display panel on a screen using a projection lens. ...
