Abstract: A display device includes a display panel including a light-emitting layer, an optical layer disposed on the display panel, and an optical lens disposed on the optical layer and including an optical lens phase retardation layer in which circularly polarized light provided from the optical layer is converted into linearly polarized light. The optical layer includes a first phase retardation layer disposed on the display panel, a selective reflection layer disposed on the first phase retardation layer and configured to output linearly polarized light by transmitting light coincident with a polarization axis and to reflect light not coincident with the polarization axis, and a second phase retardation layer disposed on the selective reflection layer in which the linearly polarized light incident from the selective reflection layer is converted into the circularly polarized light.

Abstract: A display device includes: a display unit; and a color converter on the display unit and including a color converting layer and a transmission layer, a bank between the color converting layer and the transmission layer, a first layer on the color converting layer, the transmission layer, and the bank, a second layer on the first layer, a third layer on the second layer, and a color filter on the third layer. The first layer includes a first sub-layer with a first refractive index equal to or greater than about 1.4 and less than about 1.8, and a second sub-layer with a second refractive index equal to or greater than about 1.8 and equal to or less than about 2.0. The second layer has a refractive index smaller than those of the first layer. The third layer has a refractive index greater than that of the second layer.

Abstract: A method of manufacturing a display device includes providing a mother substrate including a first cell region, a second cell region, and a peripheral region. First alignment keys arranged in a first direction in the peripheral region on the mother substrate is formed such that the first alignment keys are adjacent to a first side portion of each of first and second light emitting structures, while forming the first and second light emitting structures in the first and second cell regions on the mother substrate, respectively. A photoresist is formed in a second direction on the first and second light emitting structures by using a coater such that the photoresist does not to overlap the first alignment keys. The mother substrate is rotated at a preset angle. A light is irradiated to the photoresist by moving an exposer in a direction in which the first alignment keys are arranged.
