Provided is a color filter having improved light efficiency and color reproducibility. The color filter includes: a substrate having a plurality of pixel areas and a light blocking area surrounding the plurality of pixel areas; a light blocking layer on the light blocking area; a first color conversion layer on a first pixel area among the plurality of pixel areas and configured to convert incident light into light of a first color; a first color filter layer between the substrate and the first color conversion layer and configured to selectively transmit the light of the first color emitted from the first color conversion layer; and a light reflection layer between the first color conversion layer and the first color filter layer and including a reflective material.

Color filter and display device comprising same

A display device includes pixel circuits disposed on a substrate, each of the pixel circuits comprising a transistor and a storage capacitor, display elements electrically connected to the pixel circuits, and a metal layer disposed between the substrate and the pixel circuits, the metal layer comprising through-holes, wherein the through-holes of the metal layer include a first through-hole, and a second through-hole disposed adjacent to the first through-hole.

Display device and electronic apparatus

A color filter includes a substrate including pixel areas and a light-shielding area which is disposed between adjacent pixels areas; and a color conversion layer which color-converts incident light of an incident color and emits color-converted light toward the substrate, the color conversion layer including a first color conversion pattern in a first pixel area among the pixel areas and with which the incident light of the incident color is converted into light of a first color; and a second color conversion pattern in a second pixel area among the pixel areas and with which the incident light of the incident color is converted into light of a second color; and a partition wall in the light-shielding area and between the first color conversion pattern and the second color conversion pattern, the partition wall including a light-scattering material which scatters light incident thereto.

Color filter and display apparatus including the same

A display apparatus includes a light guide member disposed below a display member. A light source configured to generate light is disposed adjacent to the light guide member. The light guide member includes a plurality of diffraction on the light guide member. The diffraction patterns are spaced apart from each other in the first direction. The plurality of diffraction patterns diffract incident light, which is incident at an incident angle, to change the incident light to diffraction light having a diffraction angle. The incident angle is defined as an angle between the incident light and a normal line that is perpendicular to a top surface or a bottom surface of the light guide member. The diffraction angle, which is defined as an angle between the diffraction light and the normal line, has a magnitude less than that of the incident angle.

Backlight unit and display apparatus including the same

A display device includes a display panel, a light guide plate disposed under the display panel, a light source disposed adjacent to one side surface of the light guide plate that generates a first light, a first refractive layer disposed between the light source and the one side surface of the light guide plate that has a refractive index greater than a refractive index of the light guide plate, and a second refractive layer disposed between the display panel and the light guide plate that has a refractive index less than the refractive index of the light guide plate. The first refractive layer includes a convex portion that protrudes into the one side surface of the light guide plate.

Backlight unit and display device having the same

A broadband light absorber and a display apparatus including the same. The broadband light absorber includes a substrate and a pattern layer having a mesh structure including a plurality of openings, wherein any neighboring openings among the plurality of openings are non-uniform and wherein the plurality of openings comprise first openings haying a first size and second openings haying a second size different from the first size, the first openings and the second openings being alternately arranged in a first direction.
