Embodiment Construction

[0026] It has been mentioned in the background technology that the light emitted from the backlight module is repeatedly reflected by the metal film on the lower substrate to the interface between the edge of the glass and the air. When the incident angle is greater than the critical angle of the glass to the air, then The light will be completely reflected into the glass medium, so as to reach the contact interface between the glass surface and the air. At this time, the incident angle of the light is smaller than the critical angle of the glass to the air, so there is no total reflection on the contact interface. At this time, due to There is usually a gap between the extension of the outer frame and the upper polarizer, which leads to edge light leakage. The basic principle of total reflection of light is that light is injected from an optically dense medium into an optically sparse medium, and the incident angle of light is greater than the critical angle, so total reflecti...

Abstract

The invention discloses a liquid-crystal display device and a manufacturing method of the liquid-crystal display device as well as a shading element processing device. The liquid-crystal display device comprises shading elements which are arranged on the lateral edges of an upper baseplate and a lower baseplate. A total reflection phenomenon which appears on a contacted border between a glass baseplate and air is avoided and the defect of marginal light leakage of the liquid-crystal display device is eliminated.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device, a manufacturing method thereof, and a light-shielding element processing device. Background technique [0002] A liquid crystal display (liquid crystal display, LCD) has gradually become one of the fastest-growing flat panel displays due to its thinness and other advantages. The liquid crystal display device uses liquid crystal material to display images, and the liquid crystal changes the transmittance according to the voltage applied to it, so as to realize the display of different gray scales, and then cover a layer of color film in the direction of light emission to achieve Color display of pictures or videos. Specifically, a complete liquid crystal display panel must have a backlight module, a polarizer, a thin-film transistor (TFT) lower substrate, a color filter (CF) upper substrate, and a liquid crystal molecule layer filled in a box...
