Abstract
An illumination apparatus used in non-light emission transparent display devices includes a base material, light emitting elements arranged two dimensionally on the surface of the base material, a drive section driving the light emitting elements, and a light emitting intensity control section controlling a light emitting intensity of the light emitting elements. An arrangement of the light emitting elements is such that a density at ends of the base material is high compared to that in a center part thereof, and the ends have a high density in regions where the base temperature is high and the center part has a high density in regions where the base material temperature is high.

An illumination apparatus used in a non-light emission and transparent display device, comprising a base material, light emitting elements arranged in a straight line on a surface of the base material, a drive section driving the light emitting elements, and a light emitting control section controlling light emitting intensity of the light emitting elements,
- a density of arranging the light emitting elements on the base material at end parts thereof being higher than a density at a center part,
- the density of arranging the light emitting elements at the end parts being higher, in those regions where the base material temperature is high, than the density in those regions where the base material temperature is low, and
- the density of arranging the light emitting elements at the center part being higher, in those regions where the base material temperature is high, than the density in those regions where the base material temperature is low.
