Embodiment Construction

[0047] The inventors have discovered through research that: in a liquid crystal display device, the liquid crystal display panel and the backlight module are usually fabricated separately, and then the liquid crystal display panel and the backlight module are assembled into modules. A liquid crystal display panel usually includes upper and lower substrates and upper and lower polarizers attached to the outer sides of the upper and lower substrates. The outer side of the polarizers includes a protective film for protecting the polarizers. When assembling the traditional LCD panel and the backlight module, it is necessary to tear off the protective film of the lower polarizer first, then align the LCD panel and the backlight module up and down and fix them through a front frame. However, in the front Before pressing and fixing the frame, it is necessary to tear off a corner of the protective film of the upper polarizer, so that the protective film can be removed smoothly before s...

Abstract

A liquid crystal display structure includes a liquid crystal display panel, a backlight assembly arranged on one side of the liquid crystal display panel, and a polarizer arranged on a side of the liquid crystal display panel opposite from the backlight assembly. The liquid crystal display structure includes a display area and a non-display area surrounding the display area. The polarizer includes a first section and a second section, the first section being located in a central portion of the polarizer and corresponding in position to the display area, and the second section surrounding the first section and corresponding to the non-display area. The second section of the polarizer defines at least one through hole between every two adjacent corners of the second section.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] A liquid crystal display device (LCD) is one of the most widely used flat panel displays. A liquid crystal display device includes two panels provided with field generating electrodes such as pixel electrodes and common electrodes and a liquid crystal layer interposed therebetween. The liquid crystal display device displays images by applying a voltage to the field generating electrode to generate an electric field in the liquid crystal layer. The electric field determines the orientation of the liquid crystal molecules in the liquid crystal layer, thereby changing the polarization of the incident polarized light and changing the transmittance of the liquid crystal display device. So that the liquid crystal display device can display images according to the change of transmittance. [0003] Generally, a liquid crystal display device includes a liquid crystal panel...
