Claims

[Scope of utility model registration request]

A liquid crystal display section consisting of a liquid crystal display surface and a liquid crystal drive circuit, a row light emitting element array, a row light receiving element array, and a column light emitting element array that detect the position of a finger or the like pointing perpendicularly to the liquid crystal display surface and illuminate the liquid crystal display surface. a non-contact position detection section consisting of an element array, a column light receiving element array, and a position detection circuit; a control signal circuit section that controls the display contents of the liquid crystal display section based on input from the non-contact position detection section; and a liquid crystal display section. It is characterized by being composed of a power supply unit that supplies power to the non-contact position detection unit and the control signal circuit unit, and an outer box that houses the liquid crystal display unit, the non-contact position detection unit, the control signal circuit unit, and the power supply unit. A liquid crystal display device.
