Abstract: A display device includes a display panel, a sensor layer on the display panel, and a light control layer on the sensor layer. The display panel includes a first pixel area emitting a first light and a second pixel area emitting a second light having a light emission wavelength different from a light emission wavelength of the first light, a light emitting element on a base substrate, and an encapsulation layer on the light emitting element. The light control layer includes a high refractive pattern that overlaps the first pixel area, does not overlap the second pixel area, and includes a first colorant, and an overcoat layer covering the high refractive pattern and overlapping the first pixel area and the second pixel area. A refractive index of the high refractive pattern is higher than a refractive index of the overcoat layer.

Abstract: A display module is divided into a light-emitting region and a non-light-emitting region. The display module includes a base layer, a display element layer, an encapsulation substrate on the display element layer, and a light control layer including a colorant. The display element layer includes a pixel defining film having an opening defined therein to correspond to the light-emitting region, light-emitting elements adjacent to the pixel defining film, a first electrode exposed by the opening, a hole transport region on the first electrode to correspond to the light-emitting region and on the pixel defining film in the non-light-emitting region, a light-emitting layer on the hole transport layer to correspond to the light-emitting region, an electron transport layer on the light-emitting layer to correspond to the light-emitting region and on the hole transport layer in the non-light-emitting region, and a film formation suppression layer in the non-light-emitting region.

Abstract: A display device may include a display panel, a light control layer disposed on the display panel, and a low reflection layer disposed on the light control layer. The low reflection layer may include a first color material having a first molar extinction coefficient and a second color material having a second molar extinction coefficient. A functional group of the second color material maybe different from a functional group of the first color material. The first molar extinction coefficient may be smaller than the second molar extinction coefficient, and a content of the first color material may be smaller than a content of the second color material. The display device has improved color reproduction and reduced reflectance of external light due to the low reflection layer that includes color materials having different molar extinction coefficients.
