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.

Abstract: A method of manufacturing a display device includes forming a light emitting structure on a substrate and forming a thin film encapsulation layer on the light emitting structure by chemical vapor deposition equipment. The forming the thin film encapsulation layer includes forming a first inorganic layer and performing a first plasma treatment on a first portion of the first inorganic layer which is opposite to a second portion of the first inorganic layer facing the light emitting structure. A first raw material in the forming the first inorganic layer includes hydrogen. A second raw material in the performing the first plasma treatment exclusively consists of hydrogen.
