An organic EL display panel includes light-reflective electrodes, a first red light-emitting layer, a green light-emitting layer, a first blue light-emitting layer, a second red light-emitting layer, a charge generating layer, a second blue light-emitting layer, and a light-transmissive electrode. In a red and a white sub-pixel region, a first optical length is from 20 nm to 50 nm, and a second optical length is from 210 nm to 230 nm. In a green sub-pixel region, the first optical length is from 20 nm to 50 nm, and the second optical length is from 240 nm to 295 nm. In a blue sub-pixel region, the first optical length is from 20 nm to 60 nm, and the second optical length is from 195 nm to 205 nm.
