PROBLEM TO BE SOLVED: To provide a pattern light-emitting display capable of demonstrating excellent visibility and attractiveness in all of the conditions of follow light in daytime, at night, and of backlight in daytime, having a simple structure, easy in assembling and maintenance, and light-weight.SOLUTION: A pattern light-emitting display includes a light-transmitting pattern plate, an organic electroluminescence element plate disposed on the back surface side of the pattern plate, and a light-transmitting back plate disposed on the back surface side of the organic electroluminescence element plate. The organic electroluminescence element plate has a light transmissivity Tof 65% or more at a wavelength of 550 nm in a light non-emission state. |
