The invention discloses an optical alignment film and a manufacturing method thereof. The optical alignment film comprises an optical alignment material layer and is provided with at least one pixel corresponding part. The manufacturing method of the optical alignment film includes a fully exposure manufacturing technology and a partially exposure manufacturing technology, and alignment on the pixel corresponding part can be conducted from different directions through the fully exposure manufacturing technology and a partially exposure manufacturing technology. The fully exposure manufacturing technology includes full irradiation to the pixel corresponding part. The partially exposure manufacturing technology includes partial irradiation to the pixel corresponding part. The pixel corresponding part which is after the fully exposure manufacturing technology and the partially exposure manufacturing technology is provided with a primary irradiation area and a secondary irradiation area, wherein the primary irradiation area is exposed once, the secondary irradiation area is exposed twice, and partial pixel corresponding part is located in the secondary irradiation area.
Description
technical field [0001] The present invention relates to a liquid crystal display, and in particular to a photoalignment film and a manufacturing method thereof. Background technique [0002] The liquid crystal display panel is mainly composed of an active element array substrate, an opposite substrate and a liquid crystal layer. When an electric field is applied between the opposite substrate and the active element array substrate, the liquid crystal molecules in the liquid crystal layer will be deflected by the electric field, so that the liquid crystal layer has light transmittance corresponding to the electric field. In this way, the liquid crystal display panel can display different grayscale images according to the magnitude of the electric field between the opposite substrate and the active element array substrate. In order to make the liquid crystal molecules react quickly and satisfy the requirement of wide viewing angle, it is necessary to make the liquid crystal m...
