How many layers can a liquid crystal display consist of?

The bottom white one is the reflector, which is used to control the light to be emitted only in the direction of the cell

The transparent resin plate is the light guide plate, which is responsible for turning the point light source of the LED into a surface light source

The above is a diffuser to make the light source more uniform

Above are two prism sheets, which concentrate the light source and improve the utilization rate of the light source

The black one at the top is the key point. The display depends on it. It is the cell, and the structure inside is complicated.
