Description

【Technical field】 [0001] The present invention relates to a display panel and a manufacturing method thereof, and in particular to a liquid crystal display panel and a manufacturing method thereof. 【Background technique】 [0002] The known multi-domain vertically aligned (MVA) liquid crystal display panel utilizes the configuration of an alignment structure to make the liquid crystal molecules in different regions tilt at different angles, so as to achieve the effect of wide viewing angle. The alignment structure includes alignment protrusions and alignment slits disposed on the electrodes. However, the pouring directions of the liquid crystal molecules located around the alignment bumps and the alignment slits are often discontinuous, resulting in light leakage and lowering the display contrast of the liquid crystal display panel. If in order to reduce the degree of light leakage, a light-shielding layer is disposed corresponding to the alignment bumps or alignment slits, ...
