Abstract:
This transparent display device comprises: a transparent substrate (10); a plurality of light emitting units (20) disposed on the transparent substrate (10); a wiring part (40) connected to each of the light emitting units (20); and a control unit (60) that is composed of an electric circuit board, supplies current to the light emitting units (20) through the wiring part (40), and to which the current returns from the light emitting units (20). The light emitting units (20) and the wiring part (40) are disposed in a display region (A). Each of the light emitting units (20) includes a light emitting diode having an area of 1 mm2 or less. In regard to the wiring part (40) disposed in the display region (A), the display region (A) being divided into a plurality of regions each having the same prescribed area, the variation in the product of the length and reciprocal of the cross-sectional area of the wiring part (40) in each of the divided regions with respect to the average of all the divided regions is no more than 30%. The area of regions with a visible light transmittance of 20% or less is 60% or less.
