Curved liquid crystal display panel

A curved liquid crystal display panel, which is formed by curving a liquid crystal display panel, the 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 arranged between the TFT substrate and the CF substrate;

• the TFT substrate comprising a first base plate, a first black matrix formed on the first base plate, a plurality of light-shielding metal frame formed on the first base plate and the first black matrix, an insulation layer formed on the first base plate and covering the plurality of light-shielding metal frame, and a plurality of data lines, a plurality of gate scan lines, and a pixel electrode layer formed on the insulation layer;
• the plurality of data lines and the plurality of gate scan lines circumferentially delimiting and defining a plurality of sub-pixel zones, the plurality of light-shielding metal frame being respectively arranged in the plurality of sub-pixel zones, the pixel electrode layer comprising a pixel electrode corresponding to each of the sub-pixel zones, the pixel electrode comprising a multi-domain structure, the multi-domain structure comprising a trunk portion and branch portions, the first black matrix comprising a black light-shielding strip corresponding to each of the sub-pixel zones;
• wherein when the liquid crystal display panel is in a planar state, the black light-shielding strip is located under the trunk portion of the pixel electrode and the black light-shielding strip has a width that is less than or equal to a width of the trunk portion;
• wherein when the liquid crystal display panel is in a curved state, in two opposite side zones of the curved liquid crystal display panel, the CF substrate is sideways shifted with respect to the TFT substrate such that a dark pattern zone is generated at a location above one side of the trunk portion of the pixel electrode and the black light-shielding strip shields the dark pattern zone;
• and in a central zone of the curved liquid crystal display panel, the black light-shielding strip shields a portion of a normal zone having the same width as that of the dark pattern zone, whereby brightness of the curved liquid crystal display panel is made homogenized;
• the CF substrate comprising second base plate and a color resist layer formed on the second base plate;
• wherein the light-shielding metal frame comprises a first light-shielding section located under the trunk portion and a second light-shielding section located on a circumference of the sub-pixel zone, the first light-shielding section having a width that is less than the width of the trunk portion;
• wherein the width of the black light-shielding strip is substantially equal to the width of the trunk portion;
• wherein in the planar state, the black light-shielding strip is located exactly under the trunk portion and two opposite ends of the black light-shielding strip are respectively in alignment with two ends of the trunk portion;
• wherein the first base plate comprises a groove and the first black matrix is arranged in the groove.
