Problems solved by technology

In the case of electrification, an inclined electric field will be formed between the three electrodes, and the liquid crystal molecules will deviate from their vertical position under the action of the two electric fields, and will be inclined, so that the liquid crystal display panel can transmit light; however, a part of the upper layer (close to The liquid crystal molecules in the liquid crystal layer of the color filter substrate) have a large distance from the pixel electrode, so the electric field force is reduced, and the angle away from its vertical position is small, which will lead to a low light transmittance of the liquid crystal display panel.
