Liquid crystal display device

Abstract

The invention discloses a liquid crystal display device. The device includes a liquid crystal display panel and a backlight module, a flexible substrate of the liquid crystal display panel includes aplanar region and a step region located on at least one side of the planar region, a light guide plate in the backlight module comprises a light emitting area and a bending area located on at least one side of the light emitting area, the light emitting area is disposed right against the planar area of the flexible substrate for performing a display function, the bending area and the step area arebent and attached to the surface of one side, away from a liquid crystal layer, of the backlight module, the problems that a frame area for accommodating the step region and a light source is required to be disposed on a liquid crystal display device, so that the frame width of the liquid crystal display device is large and the screen-to-body ratio is small are solved, and it is achieved that thestep area and the light source partially overlap with the display area of the liquid crystal display panel in a direction perpendicular to the backlight module, thereby reducing the frame width of the liquid crystal display device and increasing the screen-to-body ratio.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] The liquid crystal display device has the advantages of energy saving, thinness, and exquisite picture, and has been widely used in the field of display technology. With the continuous improvement of people's quality of life, people have higher and higher requirements for liquid crystal display devices, and liquid crystal display devices with narrow borders and full screens have become the focus of people's pursuit. [0003] The existing liquid crystal display device includes a liquid crystal display panel and a backlight module, wherein the liquid crystal display panel needs to be provided with a driving array and a control chip to provide driving voltage to the liquid crystal molecules in the display area. Wherein, the driving array is arranged in the display area, the control chip and the fan-out wiring electrica...

AI Technical Summary

Problems solved by technology

Wherein, the driving array is arranged in the display area, the control chip and the fan-out wiring electrically connected with the control chip are arranged in the frame area of ​​the liquid crystal display device; at the same time, the light source in the backlight module is also located in the frame area of ​​the liquid crystal display device, and the light source is connected to the frame area of ​​the liquid crystal display device. There also needs to be a certain distance between the light incident surfaces of the light guide plate to increase the light mixing effect. Therefore, the existing liquid crystal display device has a large frame width and a small screen-to-body ratio, which is difficult to meet the design requirements of the narrow frame of the liquid crystal display device.
