ABSTRACT:
A thin film electroluminescent element includes a luminous layer for emitting light by applying a voltage to the luminous layer through an electrode, the electrode being made of a metal; and a material for scattering the light and disposed on an end face of the luminous layer. A large picture polychromatic display apparatus includes a thin film electroluminescent element; and a material for scattering light and disposed in a luminous portion for emitting the light on an end face of the electroluminescent element, the light-scattering material forming a picture element. The display apparatus may include a thin film electroluminescent element formed by sequentially stacking a metallic electrode, an insulating layer and a luminous layer with each other on a glass substrate; and a material for scattering light and disposed on an end face of the element by scribing the element in the longitudinal direction thereof, the display apparatus being formed by combining a plurality of such elongated elements with each other, each of the elongated elements being provided with the light-scattering material. In the element, a plurality of luminous layers having different luminous wavelength characteristics are stacked with each other, and an insulating layer and a metallic electrode are disposed on both sides of the luminous layers. The light-scattering material mixes the lights emitted from the luminous layers with each other by the scattering of the lights and is disposed on the end faces of the luminous layers.
