Abstract: The present disclosure relates to a light emitting display device. A light emitting display device according to the present disclosure includes a substrate, a first pixel and a second pixel neighboring each other on the substrate. The display device includes a planarization layer covering the first pixel and the second pixel. The display device includes a bank on the planarization layer. The display device includes a first slit at the planarization layer between the first pixel and the second pixel. The display device includes a second slit at the bank between the first pixel and the second pixel. The first slit and the second slit are arranged to be offset by a selected distance.

Abstract: A transparent display device has improved transparency. The transparent display device includes a substrate having transmissive areas and a non-transmissive area disposed between the transmissive areas. A first signal line is provided in the non-transmissive area and extended in a first direction. A second signal line is provided in the non-transmissive area and extended in a second direction. A first pixel includes a first subpixel, a second subpixel and a third subpixel, which are overlapped with at least a portion of the second signal line and disposed substantially in a line in the second direction. A second pixel disposed adjacent to the first pixel includes a first subpixel, a second subpixel and a third subpixel, which are overlapped with at least a portion of the second signal line and disposed substantially in a line in the second direction. The first pixel and the second pixel are disposed between two transmissive areas.

Abstract: The present invention relates to a composite optical sheet, characterized in that two or more optical sheets regularly arranged with micro lenses each having a lens pitch of 1˜30 ?m are stacked to prevent the moire phenomenon, and brightness-improving sheets with different sizes of lenses are formed to maximize the brightness.

Abstract: The present invention relates to a regular pattern optical sheet, the sheet including a transparent flat plate-shaped body, and a plurality of lens-shaped patterns regularly formed at one surface of the body, each having a same size of more than 0.1 ?m but smaller than 25 ?m in diameter, an angle formed by at least one line of lines straightly connecting each center of the plurality of lens-shaped patterns, wherein a horizontal axis of an LCD pixel formed at an upper surface of the body is more than 5.5° but smaller than 9.5°, and a discrete distance between the plurality of lens-shaped patterns is more than 5% but smaller than 15% of a diameter of the lens-shaped pattern.
