Abstract

The invention provides a liquid crystal display device. The device comprises a liquid crystal panel and a backlight module, wherein the backlight module is positioned under the liquid crystal panel, and comprises an iron frame, a light guide plate and a light source; the iron frame is provided with a horizontal frame edge and a vertical frame edge, the horizontal frame edge and the vertical frame edge form an accommodating space, and the vertical frame edge is used for carrying the liquid crystal panel and adhered to the liquid crystal panel by virtue of a first double faced adhesive tape; the light guide plate is positioned in the accommodating space, and is arranged above the horizontal frame edge of the iron frame; and the light source is accommodated in the iron frame. According to the liquid crystal display device, a rubber frame can be saved to narrow the frames of the liquid crystal display device.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a narrow frame liquid crystal display device. Background technique [0002] With the rapid development of network and wireless communication technology, informatization is gradually popularized among individuals. Therefore, portable information products, such as notebook computers, mobile phones, digital cameras and personal data assistants, etc., are developing and growing rapidly. Liquid Crystal Display (LCD for short) has the advantages of thinness, light weight, low power consumption, no radiation pollution, and compatibility with semiconductor manufacturing processes, etc. The rise of the product has made its product application grow by leaps and bounds in just 30 years. [0003] A general liquid crystal display (LCD) is composed of a liquid crystal panel and a backlight module. The backlight module not only provides the light source for the LCD panel, but also the plastic...
