Abstract: A display device includes: a plurality of organic layers each made of an organic material and each having a predetermined modulus of elasticity and a predetermined thickness; and a plurality of inorganic layers each made of an inorganic material and each having a predetermined modulus of elasticity and a predetermined thickness. The plurality of organic layers and the plurality of inorganic layers are stacked together to constitute a device body which forms the display device. A quotient obtained by dividing the sum of flexural rigidities of the plurality of inorganic layers by the sum total of the sum of flexural rigidities of the plurality of organic layers and the sum of the flexural rigidities of the plurality of inorganic layers is 0.78 or higher and 1 or lower.
