Abstract: A display device includes a pixel including sub pixels representing different colors. Each of the sub pixels includes a first light emitting diode and a second light emitting diode. A touch sensor unit is on the first light emitting diode and the second light emitting diode of a sub pixel and the touch sensor unit includes first openings overlapping an emission area of the first light emitting diode. First lenses are disposed within the first openings of the touch sensor unit and have a viewing angle of a first value and overlap the emission area of the first light emitting diode of the sub pixel. A second lens is on the touch sensor unit and has a viewing angle of a second value that is greater than the first value and the second lens overlaps an emission area of the second light emitting diode of the sub pixel.

Abstract: The present disclosure relates to a light shutter panel and a transparent display apparatus having the same. The light shutter panel comprises: a first light shutter panel and a second light shutter panel. Each of the first and second light shutter panels includes: a lower electrode plate, an upper electrode plate, a shutter layer, transparent spacers and a black ink. The lower electrode plate and the upper electrode plate are attached as facing each other. The shutter layer is disposed between the lower electrode plate and the upper electrode plate. The shutter layer includes a maximum light transmitting portion, a minimum light blocking portion, an ink storage portion and an electric field guide. The electric field guide is disposed between the ink storage portions. The transparent spacers maintain the gap between the lower electrode plate and the upper electrode plate. The black ink is filled into the ink storage portion.

Abstract: An optical film, a backlight unit, and a display device are provided. An optical film includes: a plurality of base layers arranged at predetermined intervals in a horizontal direction, and a plurality of barriers respectively provided between pairs of the plurality of base layers, wherein each of the plurality of barriers includes first and second films inclined with a first inclined angle with respect to a lower surface of each of the plurality of base layers, wherein the first film is configured to: transmit light polarized in a first direction, and reflect light polarized in a second direction perpendicular to the first direction, and wherein the second film is configured to phase-retard the light polarized in the first direction to the light polarized in the second direction.
