Abstract

The present invention provides a liquid crystal display device which can enlarge an effective display region without lowering a light quantity and can reduce a thickness and a weight thereof. A thin-film spacers having resiliency is arranged in the inside of a metal frame for holding a liquid crystal display panel. The spacer includes protrusions and a liquid crystal display panel is fixed by utilizing the resiliency of the protrusions. Further, by using resin material having high reflectance as a material of the spacer, it is possible to suppress the leaking of light from a light guide plate so that the lowering of luminance of the liquid crystal display device can be obviated.

Description

technical field [0001] The present invention relates to a liquid crystal display device in which a liquid crystal display panel and a metal frame with a backlight as an illumination light source are assembled on the back, and in particular relates to a liquid crystal display device capable of enlarging the effective display area and effectively utilizing the backlight while reducing thickness and weight A liquid crystal display device that improves brightness by illuminating light. Background technique [0002] A liquid crystal display device is a device that forms an electronic latent image on a liquid crystal display panel and visualizes the electronic latent image by illuminating light. There are known devices that utilize external light as an illumination light device and that incorporate an illumination light source that irradiates light on the back or front of a liquid crystal display panel. For liquid crystal display devices used as display means for small electronic...
