Abstract

The invention relates to a liquid crystal display device. A very thin resin spacer with elastic force is integrally arranged inside the metal frame (1) to hold the liquid crystal display panel (5). The resin spacer has a protrusion (2a), and the liquid crystal display panel (5) is fixed by the elastic force of the protrusion (2a). In addition, the resin spacer is formed of a resin material with high reflectivity, which can suppress the light leakage of the light guide plate (6) and avoid the decrease of the brightness of the liquid crystal display device. The present invention can provide a thinner and lighter liquid crystal display device that expands the effective display area without reducing the amount of light.

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...
