A transreflective liquid crystal display is a liquid crystal display (LCD) that reflects most of the sunlight the monitor is exposed to, and automatically increases or decreases the light emanating from the screen depending on how much light shines on it. Therefore, it reduces the need for manual light adjustment of the screen.

Transreflective liquid crystal displays use a retroreflector to transmit light when external sources of light are available, such as the sun or a lamp, and illuminate the screen well. When these sources are available but do not illuminate well, the display transmits its own light from a backlight at the rear of the display.
