IMAGE DISPLAY WITH FUNCTION FOR TRANSMITTING LIGHT FROM SUBJECT TO BE OBSERVED

摘要

An image display with a function for transmitting light from a subjected to be observed comprises a display element, which includes a pair of transparent substrates with an electrode, a liquid crystal layer, which is sandwiched between a pair of transparent substrates and can be in a light transmitting state and a light scattering state, and is in a light transmitting state when a voltage is not applied and in a light scattering state when a voltage is applied; a light source which makes light substantially parallel with the surface of the liquid crystal layer impinge on the liquid crystal layer; and a timing control circuit, which is interlocked with the state of light exit to the liquid crystal layer in the light source, in a state where external light exists, and brings at least a part of the display surface of a display element into a light scattering state or a light transmitting state.
