Liquid crystal display device and making method thereof

Abstract

The invention provides a liquid crystal display device and a making method thereof. According to the liquid crystal display device, a quantum rod orientation layer (2) is arranged for conducting parallel orientation on a quantum rod layer (3), and the quantum rod layer (3) obtained after orientation can replace a traditional lower polarizer plate. The making method of the liquid crystal display device includes the steps that the quantum rod orientation layer (2) is prepared through an inclined vacuum evaporation process, a plurality of trenches (21) which are arranged in parallel and are perpendicular to a penetrating shaft of an upper polarizer plate (7) in the extension direction are formed in the quantum rod orientation layer (2), then the quantum rod layer (3) is prepared on the quantum rod orientation layer (2), the direction of long shafts of multiple quantum rods (31) in the prepared quantum rod layer (3) is parallel to the extension direction of the trenches (21), and in another word, the quantum rod layer (3) conducts parallel orientation. The quantum rod layer (3) obtained after orientation can replace the traditional lower polarizer plate, so that light transmittance and the backlight utilization rate can be raised, display brightness is increased, and the production cost is saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device and a manufacturing method thereof. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook Computer screens, etc., dominate the field of flat panel displays. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. A traditional liquid crystal display panel generally includes: an array substrate, a color filter substrate disposed opposite to the array substrate, and a liquid crystal layer disposed between the array substrate and the color filter substrate. A lower polarizer is attached to the array substrate,...

AI Technical Summary

Problems solved by technology

[0004] For the existing liquid crystal display device, the transmittance of the upper and lower polarizers to the backlight source can only reach less than 50% in theory, and the light passes through the electrode layer, color filter, liquid crystal layer and glass substrate of the liquid crystal panel. After waiting for the structure, the display brightness actually visible to the user is only less than 10% of the brightness of the light emitted by the backlight source, and the light penetration rate and the utilization rate of the backlight source are quite low.
