A liquid crystal display (LCD) includes several transparent material layers and several non-transparent material layers that are disposed in a stacked mode. The LCD also has a local transparent region, and no non-transparent material is applied to the several non-transparent material layers in the local transparent region. This forms a transparent channel in the local transparent region along a stacking direction. An optical component is completely or partially disposed in the transparent channel of the LCD display. The optical component may be a camera, an ambient light sensor, an optical fingerprint sensor, or another component disposed under the display by using the local transparent region on the LCD display.
