摘要： 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.

摘要： A display device includes: a first base having a display area; light-emitting elements on the first base; and an encapsulation layer over the light-emitting elements. The encapsulation layer includes: a first inorganic layer; an organic layer on the first inorganic layer; and a second inorganic layer on the organic layer. The first inorganic layer includes: a first buffer layer on the light-emitting elements; a first barrier layer on the first buffer layer; a first porous layer on the first barrier layer; a second barrier layer on the first porous layer; and a second buffer layer on the second barrier layer. A refractive index of the first buffer layer, the first barrier layer, and the first porous layer are different from one another, and the refractive index of the first porous layer is smaller than the refractive index of the first buffer layer and the first barrier layer.
