    • A light emitting apparatus including a plurality of light emitting devices for different colors and having a simple structure with small variations in luminous brightness of each of the light emitting devices for the different colors is provided, and electronic equipment provided with such a light emitting apparatus is also provided. The light emitting apparatus is configured into a display apparatus 10 which comprises: a TFT circuit board (counter substrate) 20; red light emitting devices 1R provided on the TFT circuit board 20 and emitting a light of a red luminescent color (R); green light emitting devices 1G provided on the TFT circuit board 20 and emitting a light of a green luminescent color (G); and blue light emitting devices 1B provided on the TFT circuit board 20 and emitting a light of a blue luminescent color (B); and wherein roughness is formed on an interface between a hole transport layer 4 and a red light emitting layer 5R in each of the red light emitting devices 1R, while no roughness is formed on an interfaces between a hole transport layer and a light emitting layer in each of the green light emitting devices 1G and the blue light emitting devices 1B. With these structures, it is possible to make the luminous brightness in each of the light emitting devices 1R, 1G and 1B for the respective colors substantially equal to each other when substantially the same voltage is applied thereto.
