The present invention relates to a display element and a method of fabricating the same, and more particularly to a liquid crystal display panel and a method of fabricating the same.

For the rapid advancement of the multimedia society, most of them benefit from the dramatic advancement of semiconductor components or human-machine display devices. As for the display device, a flat display device having superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation has gradually become the mainstream of the market. Among various flat display devices, the liquid crystal display panel is a flat display device with relatively mature technology.

1 is a schematic cross-sectional view of a conventional liquid crystal display panel. Referring to FIG. 1 , in the liquid crystal display, the liquid crystal display panel 100 mainly includes a color filter substrate 110 and a thin film transistor array substrate 120 . The color filter substrate 110 and the thin film transistor array substrate 120 respectively have a The electrode layer 112 and the one pixel electrode layer 122 are shared. Further, the liquid crystal layer 150 is sealed between the common electrode layer 112 of the color filter substrate 110 and the pixel electrode layer 122 of the thin film transistor array substrate 120.

When a potential is applied between the common electrode layer 112 and the pixel electrode layer 122, the liquid crystal molecules of the liquid crystal layer 150 are deflected by the potential energy, so that the liquid crystal display panel 100 has a corresponding potential energy. Light penetration rate. In this way, the liquid crystal display panel 100 can be based on the potential energy between the common electrode layer 112 and the pixel electrode layer 122. Display different grayscale screens. In addition, as shown in FIG. 1, in the liquid crystal display panel 100, a protrusion 130 as shown in FIG. 1 may be formed on the common electrode layer 112 and the pixel electrode layer 122, respectively, so that the liquid crystal in the liquid crystal layer 150 The molecules produce a multi-directional alignment effect, increasing the viewing angle range of the liquid crystal display panel 100.

Of course, the protrusion 130 may be replaced by a slit, in other words, a patterned slit is formed on the pixel electrode layer 122 of the thin film transistor array substrate 120, or at the same time. The above-mentioned protrusions and slits are designed such that the liquid crystal molecules in the liquid crystal layer 150 also produce a multi-directional alignment effect, thereby increasing the viewable viewing angle of the liquid crystal display panel and increasing the reaction speed of the liquid crystal molecules.

(burn-in) for 48 hours, and after the burn-in, the liquid crystal display panel to be tested displays a full-face gray image, and defines an image burn-in rate α=((β-γ)/γ) ×100%, where β is the brightness when the white test pattern was previously displayed, and γ is the brightness when the black test pattern was previously displayed. In other words, the larger the value of the alpha value, the less representative the performance of the liquid crystal display panel in terms of the reliability of image sticking. Conversely, the smaller the value of the alpha value, the more the liquid crystal display panel is tested in terms of the reliability of image sticking. it is good. In the prior art, the image burn-in rate of the liquid crystal display panel is preferably 6%.
