  • Patent number: 11974492
    Abstract: A display device includes a first region, a second region adjacent to a side of the first region, and a third region adjacent to another side of the first region; a display panel in the first region, the second region and the third region; a window on and overlapping the display panel; and a bonding member between the display panel and the window and in the first region, the second region and the third region. The bonding member includes a first bonding part having a first elastic modulus and in the first region, a second bonding part having a second elastic modulus and in the second region, and a third bonding part having a third elastic modulus and in the third region. The first elastic modulus is greater than each of the second elastic modulus and the third elastic modulus.

  • Patent number: 11009634
    Abstract: The present disclosure provides a structural color filter comprising: a substrate; a metal layer disposed on the substrate; and semiconductor gratings disposed on the metal layer, wherein each of the semiconductor gratings is elongated in a first direction, wherein the semiconductor gratings are arranged to be spaced apart from each other in a second direction perpendicular to the first direction, wherein the semiconductor gratings have the same thickness, wherein the thickness is smaller than a wavelength of visible-light.

  • Patent number: 10310343
    Abstract: Disclosed is a display panel in which a black matrix is formed on an upper substrate, which is disposed so as to face a lower substrate, so as to delimit each pixel area, a plurality of light control partitions is provided in the pixel area of the upper substrate, a color filter is provided in the pixel area of the upper substrate, and an overcoat layer is provided over the entire surface of the upper substrate. The light control partitions are formed in the pixel area simultaneously with the formation of the black matrix, which enables the omission of an existing light control film. Thereby, a narrow viewing angle is realized without increasing the thickness or manufacturing cost of a product.
