  • Patent number: 9329428
    Abstract: A display panel includes a first substrate and a spaced apart second substrate and a protection or other additional film attached to an outer and laterally extending major surface of the first substrate. The first substrate includes a first base substrate having a major lateral surface subdivided into a display region and a peripheral region, a color filter member disposing on the first base substrate and having a plurality of color filters, a light blocking member disposing on the peripheral region of the first base substrate and an overcoating member disposing on the color filter member and on the light blocking member and extending to cover a sidewall surface of the light blocking member. The extend overcoating member helps block charged particles from reaching the light blocking member, thus preventing discoloration of the color filter due to influx of static electricity associated with the charged particles.

  • Patent number: 9146428
    Abstract: A liquid crystal display device includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The second substrate includes a buffer layer, and the buffer layer includes a recessed portion. A spacer is disposed between the first substrate and the second substrate, such that a portion of the spacer is extended into the recessed portion. A bottom surface of the recessed portion contacts an upper surface of the spacer. A shortest line crossing a center of the bottom surface of the recessed portion is longer than a longest line crossing a center of the upper surface of the spacer, by about 14 micrometers to about 20 micrometers.

  • Publication number: 20150234224
    Abstract: Provided is an LCD device including a first substrate, a second substrate, a liquid crystal layer, a main spacer, and a supplementary spacer. The liquid crystal layer is interposed between the first and second substrates. The main spacer makes contact with the first and second substrates. The supplementary spacer makes contact with one of the first and second substrates and is spaced apart from the other. A first area ratio defined by dividing the area of a first top surface by that of a first bottom surface of the main spacer may be smaller than a second area ratio defined by dividing the area of a second top surface by that of a second bottom surface of the supplementary spacer.

  • Publication number: 20140254039
    Abstract: A color filter substrate includes a plurality of color filters and a first dummy pattern. The color filters are formed in a display area. The color filters include a plurality of colors. The first dummy pattern is formed in a peripheral area surrounding the display area. The first dummy pattern has a color identical to one of the colors. An edge portion of the first dummy pattern corresponding to an apex of the display area is rounded. Therefore, the reliability of a color filter manufacturing process may be improved, the reliability of the color filter may be improved, and the generation of stain defects having a radial shape may be prevented, so that display quality may be improved.
