Abstract:
A display apparatus, comprising:a plane optical modulation panel; a planar light source arranged facing one surface of the plane optical modulation panel and having, in a plane substantially parallel to the plane optical modulation panel, a first light emission region that includes an electroluminescent element having an optical resonator emitting light in a first color, and a second light emission region that includes an electroluminescent element having an optical resonator emitting light in a second color different from the first color, each of the light emission regions having different thickness, the light emitted from the resonators having directivity in the frontal direction thereof, a projection lens arranged at a frontal position of the plane optical modulation for enlarging images formed on the plane optical modulation panel, the projection lens projecting the images onto a screen; and a controller that independently controls electric current supplied to the electroluminescent elements of the different colors to adjust the color in which the optical modulation panel is illuminated.
