Liquid crystal display panel

A liquid crystal display panel, comprising a thin-film transistor (TFT) substrate, a color filter (CF) substrate opposite to the TFT substrate, and a liquid crystal layer interposed between the TFT substrate and the CF substrate;

• the TFT substrate comprising a first base plate and a common electrode, an insulation layer, a pixel electrode, and a first alignment film that are sequentially stacked, from bottom to top, on a surface of the first base plate that is close to the liquid crystal layer;
• the CF substrate comprising a second substrate and a second alignment film that is arranged on a surface of the second substrate that is close to the TFT substrate;
• the liquid crystal layer comprising liquid crystal molecules that are set at a pre-tilt angle for being nearly vertically aligned;
• on a plane substantially parallel to the TFT substrate and the CF substrate, the liquid crystal molecules and a direction of branch electrodes of the pixel electrode defining therebetween a direction angle θ;
• and the direction angle θ ranging from 0 to 45 degrees;
• the first alignment film and the second alignment film being alignment films that allow for vertical light alignment;
• the first alignment film being subjected to first light irradiation treatment to have the first alignment film define a first pre-tilt angle with respect to the first base plate;
• the second alignment film being subjected to second light irradiation treatment to have the second alignment film define a second pre-tilt angle with respect to the second substrate;
• and the first and second pre-tilt angles ranging from 0 to 20 degrees;
• an alignment direction of the first alignment film and an alignment direction of the second alignment film being opposite to and parallel with each other;
• and
• the liquid crystal molecules rotating horizontally upon application of an electric field for displaying;
• wherein the TFT substrate further comprises scan lines extending in a horizontal direction and data lines extending in a vertical direction, the scan lines and the data lines intersecting each other on the TFT substrate to define a plurality of sub-pixel zones, each of the sub-pixel zones being provided with a pixel electrode;
• wherein the pixel electrode comprises first and second areas, the first area comprising a plurality of first branch electrodes and a plurality of first slits between the plurality of first branch electrodes, the second area comprising a plurality of second branch electrodes and a plurality of second slits between the plurality of second branch electrodes;
• and an extension direction of the first slits and the vertical direction define therebetween a predetermined angle α and an extension direction of the second slits and the vertical direction define therebetween a predetermined angle −α;
• and
• wherein the liquid crystal molecules of the liquid crystal layer are subjected to an alignment process including individually subjecting the first alignment film and the second alignment film to exposure to ultraviolet light to allow the liquid crystal molecules to form a pre-tilt angle of a predetermined angle value, the ultraviolet light for exposure having a wavelength of 200-500 nm.
