The embodiment of the invention discloses a TN-typed liquid crystal display panel and a manufacturing method thereof, belonging to the technical field of displaying, and solving the technical problem of poor angle of view in the conventional TN-typed liquid crystal display. The TN-typed liquid crystal display panel comprises an array base plate and a color film base plate; liquid crystal mixture is arranged between the array base plate and the color film base plate; and the liquid crystal mixture contains disc-like liquid crystal with liquid crystal branched chain and nematic phase liquid crystal. The method for manufacturing the TN-shaped liquid crystal display panel comprises the following steps of: stirring uniformly the disc-like liquid crystal with liquid crystal branched chain and nematic phase liquid crystal based on a certain ratio to form the liquid crystal mixture; conducting defoaming on the liquid crystal mixture; dropwise adding the liquid crystal mixture onto an array base plate; and matching the array base plate and the color film base plate to form a liquid crystal panel. The invention is applicable to the angle of view of an enlarged TN-shaped liquid crystal display panel.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a TN type liquid crystal panel and a manufacturing method thereof. Background technique [0002] Twisted Nematic (TN) liquid crystal display is a common liquid crystal display. 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° 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. Due to the anchoring effect of the alignment film on the liquid crystal, the nematic liquid crystal molecules close to the alignment film cannot be aligned perpendicular to the panel. At this time, when viewing the liquid crystal panel from the front, the abs...
