LIGHT EMITTING DIODE, DISPLAY UNIT, AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent the deterioration by moisture and UV rays by eliminating the need for cleaning or making cleaning intervals longer, and protecting an enclosure. SOLUTION: A photocatalyst film 2 is formed on the outside surface of the translucent enclosure 1c of a light emitting diode element 1. An inorg. and translucent protective layer 3 is interposed under this photocatalyst layer at need. The photocatalyst may be formed on the outside surface of a glass cap and mounted on the light emitting diode or may be formed on the front surface of a unit transparent body disposed in front of the light emitting diode in addition to the formation on the light emitting diode. The formation of the photocatalyst on the cover of the front surface of a display unit or display device is equally good. The photocatalyst film is activated by receiving the irradiation with the UV rays to decompose the contaminants sticking thereto by an oxidation and reduction effect.
