Embodiment Construction
[0036] Regarding the problem that the aperture ratio of the liquid crystal display panel mentioned in the prior art is too low, the inventor of the present invention found that because the distance between the pixel electrode, the gate line and the data line in the prior art is too close in the direction perpendicular to the substrate, Signal crosstalk between electrodes will occur, so in order to avoid crosstalk, the pixel electrode has to be separated from the gate line and data line by a certain distance in the direction parallel to the substrate, resulting in the size of the pixel electrode being too small, so the aperture ratio cannot be improve.
[0037] Therefore, the inventor proposes a new liquid crystal display panel 201 . figure 2 is a schematic diagram of the pixel connection of the liquid crystal panel 201, image 3 It is a schematic cross-sectional structure diagram of a single pixel of the liquid crystal panel 201 . like figure 2 and image 3As shown, the ...

The invention relates to a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises two substrates between which a liquid crystal layer is sandwiched, wherein the first substrate is provided with a thin film transistor, a gate line electrically connected with the gate of the thin film transistor, a data line electrically connected with the drain electrode of the thin film transistor and a pixel electrode electrically connected with the source electrode of the thin film transistor. The liquid crystal display panel also comprises an organic film covering the gate line and the data line. The pixel electrode covers the organic film and is positioned at the two sides of the organic film with the gate line and the data line. Compared with the prior art, the invention utilizes the organic film to separate the pixel electrode from the gate line and the data line so that projection of the pixel electrode on the first substrate overlaps with the projection of the gate line and / or the data line on the first substrate, thus avoiding the defects of the prior art and improving the aperture ratio of the liquid crystal display panel.
Description
technical field [0001] The present invention relates to the field of manufacturing flat panel display devices, in particular to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] In recent years, the center of the display market is gradually occupied by Flat Panel Display (FPD). Using the FPD, a large-sized, thin and light display device can be manufactured. Such FPDs include Liquid Crystal Display (LCD), Plasma Display Panel (PDP), Organic Light Emitting Display (OLED), and the like. [0003] Liquid crystal displays have become the mainstream trend of display development due to their advantages of lightness, thinness, power saving, and no radiation. Liquid crystal displays are widely used in various electronic products such as personal digital assistants (PDAs), notebook computers, digital cameras, camcorders, and mobile phones. With the continuous development of the electronic industry, the performance of liquid crystal disp...
