Summary:PROBLEM TO BE SOLVED: To arrange closely LEDs with different light emission colors and to prevent mixed colors by efficiently radiating the light converting the light emission color of a light emission chip to the outside and enhancing light emission luminance. SOLUTION: This display is provided with the LEDs converging the light emission colors by fluorescent material and radiating them to the outside, and first LED and second LED are arranged closely horizontally on the same plane. In the first LED, the fluorescent material filled up in resin 4 sealing the whole light emitting element of the LED is moved from the resin 4 sealing the whole light emitting element into a cup 3 fixing the light emitting chip 1, and is filled up so as to cover the light emitting chip 1. The second LED is provided with the light emitting chip 1 light emitting the light capable of exciting the fluorescent material of the first LED.
