A display device having an electroluminescence element with an improved contrast ratio is provided. Stacked polarizing plates are provided on the outer side of substrates of a display device which includes a first light-transmitting substrate and a second light-transmitting substrate arranged to face each other and an electroluminescence element interposed therebetween that emits light to both the first light-transmitting substrate side and the second light-transmitting substrate side. The polarizing plates facing each other are arranged in a crossed nicol state. Furthermore, among a plurality of polarizing plates arranged to face each other, a plurality of polarizing plates which are stacked on one side or the other side of the light-transmitting substrates are arranged in a parallel nicol state. As a result, a display device with a high contrast ratio can be provided.
