Problems solved by technology

However, since the electrodes are on the same plane, the liquid crystal molecules are always parallel to the screen regardless of the state, which will reduce the aperture ratio and reduce the light transmittance. Therefore, when IPS is applied to large-size liquid crystal display devices (such as LCD TVs, etc.) More backlights will be needed, which will increase the structural complexity of the backlight module and the cost of the liquid crystal display device

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a method for preparing the array substrate and a display device. Background technique [0002] For liquid crystal display devices, since the light source that provides liquid crystal display has a certain directionality when it is output after refraction and reflection, color distortion will occur when viewing beyond a certain range, so the viewing angle is an important parameter for evaluating the performance of liquid crystal display devices . Viewing angle refers to the angle at which users can clearly observe all content on the screen from different directions. The viewing angle of the liquid crystal display device includes two indicators, the horizontal viewing angle and the vertical viewing angle. The larger the maximum viewing angle, the larger the range where the image of the liquid crystal display device can be viewed normally. The ma...
