1. An electronic device, comprising:
a liquid crystal module, having a light-transmitting area, the liquid crystal module comprising an upper polarizer, a color film substrate, a liquid crystal layer, an array substrate, and a lower polarizer from a top to a bottom in sequence, wherein thicknesses of color resist and a black matrix in a first area, at a corresponding position of the light-transmitting area, of the color film substrate are lower than thicknesses of color resist and a black matrix outside the first area, the thicknesses of the color resist and the black matrix of the first area is 10% to 60% of the thicknesses of the color resist and the black matrix outside the first area, a second area is disposed on the array substrate at a corresponding position of the light-transmitting area, and an area of the second area is smaller than an area of the first area;
a backlight module, disposed below the liquid crystal module, the backlight module is defined with a through hole corresponding to the light-transmitting area, the area of the second area is larger than an area of the through hole; and
a photographing module, disposed below the backlight module, the photographing module is disposed corresponding to the through hole, so that external light rays can be obtained by means of the through hole and the light-transmitting area.
