Abstract

Provided is a liquid crystal display panel having a microlens array, which does not easily generate deformation, peeling and the like of an optical film and has excellent display quality. A liquid crystal display panel (100A) having a microlens array is provided with a microlens array (14) arranged on the light incoming side of a liquid crystal display panel (12); a supporting body (26) arranged to surround the microlens array (14) on the light incoming side of the liquid crystal display panel (12); and an optical film (23) adhered to the liquid crystal display panel (12) through the supporting body (26). A gap (15) is formed between the microlens array (14) and the optical film (23). At least one ventilation hole (16) for connecting a space outside the supporting body (26) with the gap (15) is formed on the supporting body (26). When the ventilation hole (16) is viewed vertically to the surface of the liquid crystal display panel (12), the ventilation hole extends by being bent or in a direction diagonal to the inner surface of the supporting body (26).

Description

technical field [0001] The 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 with a microlens array. Background technique [0002] In recent years, liquid crystal display devices have been widely used as display devices for monitors, projectors, portable information terminals, mobile phones, and the like. In general, a liquid crystal display device changes the transmittance (or reflectance) of the liquid crystal display panel by using a driving signal, modulates the intensity of light from a light source irradiating the liquid crystal display panel, and displays images and characters. As 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 that enlarge and project images displayed on a liquid crystal display panel on a screen using a ...
