Abstract
A display device is provided which has high visibility by including a display element and a polarizer between a pair of substrates. The display element includes a liquid crystal element and/or a light-emitting element. The display device includes an element layer between a pair of substrates, and an organic layer serving as a polarizer or both the organic layer and a retardation layer between the element layer and the second substrate. The organic layer includes a dichroic dye in which the major axes of molecules are oriented in one predetermined direction.
