Abstract: A display device includes a first substrate in which a first pixel region and a second pixel region are defined, a second substrate including a first display element and a second display element, a first layer having a first refractive index, and a second layer having a second refractive index. The first substrate includes a first wavelength conversion layer disposed in the first pixel region and a second wavelength conversion layer disposed in the second pixel region. A total reflection critical angle between the first layer and the second layer is smaller than an incident angle of light which is emitted from the first display element and is incident into the second wavelength conversion layer.
