  • Patent number: 7598103
    Abstract: An LCD panel with mixed substrate materials and a method of making the LCD panel are presented. The LCD panel is made of a first substrate, a second substrate disposed substantially parallel to the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate includes a glass substrate, a TFT formed on the glass substrate, and a color filter formed on the TFT. The second substrate includes a plastic substrate and a common electrode formed on the plastic substrate. Forming the color filter on the TFT eliminates the need to form black matrices on the second substrate, preventing misalignment of the two substrates due to different heat sensitivities. Since there is no concern of substrate misalignment caused by heat, laser beam can be used to cut the substrates during the manufacture of the LCD panel.

  • Publication number: 20090231675
    Abstract: A display apparatus according to an embodiment includes a first substrate including a plastic material, a second substrate facing the first substrate, and a coating layer formed on at least one surface of the first substrate. The coating layer includes a first compound having an acryl-based monomer and a second compound having a silicon derivative, and prevents reflection of light from the first substrate when light is provided to the first substrate. Thus, the display apparatus may have enhanced lightness (brightness) thereby improving the display quality.

  • Publication number: 20090213297
    Abstract: A liquid crystal display contains a light source, a light guide panel that directs light from the light source towards a display panel, and optical sheets containing a diffusion sheet that spreads the light from the light guide panel and at least one prism sheet that redirects light from the diffusion sheet in a direction substantially perpendicular to the display panel. The optical sheets contain a region adjacent to the light source that has a hardened part that substantially prevents heat from being transferred to a display region of the optical sheet corresponding to the display region of the display panel and minimizes the temperature difference across the display region. The hardened part is formed on at least opposing sides of the optical sheets, overlaps a non-display region of the display panel and is bent or contains a convex part that projects towards the display panel.
