Abstract
A light-emitting device includes a plurality of pixels, a temperature-detection pixel, a temperature detector, an applied-current calculator, and a current applying unit disposed on a substrate. The pixels include display light-emitting elements for displaying information. The temperature-detection pixel is provided within a display area where the pixels are disposed and includes a temperature-detection light-emitting element for temperature detection, which is shielded by a light shielding layer and includes the same organic layer as that included in each display light-emitting element. The temperature detector detects a current value of the temperature-detection light-emitting element so as to detect the temperature thereof. The applied-current calculator calculates an electric current to be applied to the display light-emitting elements in accordance with the detected temperature so that the display light-emitting elements emit light with a predetermined luminance. The current applying unit applies the electric current to the display light-emitting elements.
