Abstract
The invention discloses a liquid crystal display panel which comprises an array substrate, a color film substrate and liquid crystal. The liquid crystal is arranged between the array substrate and the color film substrate, alignment films cover all regions of the color film substrate and regions, except for PAD regions, of the array substrate, conductive units are respectively arranged on the alignment films of the array substrate and the color film substrate, the conductive units on the array substrate are in contact with the conductive units on the color film substrate, and the PAD regions are regions where signal lines on the array substrate are subjected to compression joint with lead wires of external driving circuit boards. The invention further provides a method for manufacturing the liquid crystal display panel and a display device on the basis of the liquid crystal display panel. The liquid crystal display panel, the method and the display device have the advantages that alignment liquid is applied to the integral substrates except for the PAD regions, so that staining or Mura defects of the peripheral edges of the alignment films due to constraints on the sizes of the peripheral edges of the alignment films can be prevented; a process is changed, and the conductive units are adhered on the substrates via the alignment films, so that the problem that existing alignment films cannot be overlapped with frame sealing adhesive is solved, and the array substrate can be conductive with the color film substrate.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal panel, a manufacturing method thereof, and a display device. Background technique [0002] A TN (Twisted Nematic, twisted nematic) liquid crystal panel is a very common liquid crystal panel at present. Under the condition of not applying power to the liquid crystal, the long axis of the nematic liquid crystal molecules in the liquid crystal panel is parallel to the panel, and gradually twists and rotates 90 degrees from the array substrate to the color filter substrate; The nematic liquid crystal molecules rotate under the voltage drive, and the long axes of the nematic liquid crystal molecules are arranged perpendicular to the plate surface. [0003] The production process of the existing TN type liquid crystal panel is as follows: [0004] The first step is to prepare and obtain the array substrate and the color filter substrate, wherein the array substrate ...
