Display panel and manufacturing method thereof and display device

Abstract

The embodiment of the invention discloses a display panel and a manufacturing method thereof and a display device. The manufacturing method for the display panel comprises following steps: forming a first alignment film on a first surface of a first substrate and forming a second alignment film on a second surface of a second substrate; carrying out optical alignment on the first alignment film and the second alignment film; and adopting liquid crystal injection technology to inject liquid crystal between the first alignment film and the second alignment film and forming a box, wherein the first alignment film and the second alignment film are heated prior to injection of liquid crystal.The display panel and the manufacturing method thereof and the display device have following beneficial effects: heating treatment process enables water molecules and free-state ions, absorbed from the air, of the first alignment film and the second alignment film to volatilize during waiting time; therefore, ion concentration of alignment films is reduced such that ion concentration of the alignment films after forming liquid crystal into the box is not too high; display effect of the display panel is not affected due to high ion concentration of the alignment films; and mura and flicker and other display problems are improved and display effect off the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to display panel technologies, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, with the continuous growth of the economy, related products derived from liquid crystal display devices have covered many aspects of life, such as computers, LCD TVs, LCD screens, audio-visual equipment and smart phones. The display effect of liquid crystal products is one of the factors considered by consumers whether to buy, and the quality of the alignment film in the liquid crystal display panel of liquid crystal products will directly affect the display effect of liquid crystal products. Very important. [0003] The existing alignment film manufacturing technology of the liquid crystal display panel mostly adopts the photo-alignment technology, and the photo-alignment technology is mainly divided into three processes, the process of fo...
