Claims

[Scope of utility model registration request]

A light-emitting layer that generates EL light with a wider emission spectrum than the emission surface in response to the application of an electric field, and a light-emitting layer interposed between the light-emitting layer and the emission surface that blocks or transmits light in a narrow wavelength range only. 1. A thin film light emitting device, comprising: a color selection filter; the thin film light emitting device comprising: a color selection filter; the EL light emitting device converts the EL light into a plurality of types of light emitting colors and outputs the light from the emission surface;
