Abstract: A display system includes: a transmissive liquid crystal display panel; a light control panel having an active area with a light control area; a temperature detector provided in the liquid crystal display panel and having a detection area with a resistive element; a backlight; and a controller. A display area of the liquid crystal display panel, the active area, and the detection area overlap on an optical path of a projection light. The light control panel is disposed at such an angle that, when the light control area is in a light reflection state, the light control panel reflects external light to a position out of the optical path and different from a position of the liquid crystal display panel. The controller causes the light control area to reflect light when an output indicating that the resistive element has a predetermined temperature or higher is obtained.
