Abstract

The invention discloses a liquid crystal display device which is provided with a back plate, a light guide plate arranged on the back plate, an optical diaphragm arranged on the light guide plate, a rubber frame, a liquid crystal display panel, a driving chip and a flexible circuit board. The rubber frame is fixedly connected with the back plate so as to enable the optical diaphragm and the light guide plate to be fixed, the liquid crystal display panel is fixedly arranged on the rubber frame and comprises an upper glass substrate and a lower glass substrate, wherein the upper glass substrate and the lower glass substrate are arranged oppositely and comprise bottom surfaces, top surfaces and side surfaces for connecting the bottom surfaces and the top surfaces, and the flexible circuit board comprises metal leads and is connected to the liquid crystal display panel. The driving chip is connected with the flexible circuit board and connected to the liquid crystal display panel through the metal leads of the flexible circuit board in a coupling mode, a first wiring notch is arranged at the connecting position of the bottom surface and the side surface of the upper glass substrate, and the flexible circuit board connected to the liquid crystal display panel is wired through the first wiring notch. The liquid crystal display device enables chip on film (COF) to be hidden in the liquid crystal display device effectively and facilitates design of liquid crystal display panels without frames greatly.

Description

technical field [0001] The invention relates to the field of liquid crystal display. More specifically, it relates to a liquid crystal display device. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as light weight, thin body, power saving, etc., and thus has been widely used. With the continuous development of the production technology of liquid crystal display devices, the design of frameless liquid crystal display devices has become a trend. [0003] However, in the design of the existing frameless liquid crystal display device, the liquid crystal display panel is composed of two upper and lower glass substrates. Usually, the size of the lower glass substrate is larger than that of the upper glass substrate. The COF (Chip On Film, diaphragm) of the liquid crystal display panel The upper chip package (that is, the driver chip is fixed on the flexible circuit board) is combined with the OLB area of ​​the lower ...
