Abstract
The present invention provides a panel capable of switching between a state transparent to external light, a point light emitting state, and a surface light emitting state. Provided is a transparent panel provided with light emitting function, including: an LED die; a light transmitting substrate for LED, on which the LED die is mounted; a wiring pattern provided on a surface of the light transmitting substrate for LED and bonded to the LED die; and a light diffusing panel laminated on the light transmitting substrate for LED. The light diffusing panel includes: a pair of light transmitting substrates for liquid crystal; a liquid crystal layer sandwiched between the pair of light transmitting substrates for liquid crystal; and transparent conductive films disposed on the light transmitting substrates for liquid crystal, and is switchable between a transparent state and a light diffusion state.
