  • Publication number: 20060221291
    Abstract: A display device is presented. The display device includes first and second panels positioned substantially parallel to each other, a liquid crystal layer disposed between the first and second panels, and a sealant attaching the the first and second panels to each other and sealing in the liquid crystal layer between the two panels. A sealant portion of at least one of the first and second panels includes a rough surface, the sealant portion contacting to the sealant upon the attaching of the two panels. The rough surface in the sealant portion allows the formation of a seal between the panels that is strong enough to be is suitable for use with a flexible substrate (e.g., a plastic substrate).

  • Publication number: 20060098154
    Abstract: A method of manufacturing a flexible display device includes adhering a first substrate to a supporter, half cutting the first substrate to divide the first substrate into a first region and a second region, assembling the first substrate and a second substrate facing the first substrate, combining the first and second substrates, and removing the second region of the first substrate from the first region of the first substrate.

  • Publication number: 20060082705
    Abstract: A display device includes a first panel and a second panel facing each other, a liquid crystal layer and a member for determining a tilt direction of liquid crystal molecules of the liquid crystal layer. The display device has a reflective area and a transmissive area. The liquid crystal layer is interposed between the first panel and the second panel. The member is disposed at a portion of the second panel corresponding to the reflective area. The display device realizes a multi-domain structure and prominent reflective efficiency is obtained by utilizing a projection area as a reflective area.

  • Publication number: 20060055848
    Abstract: A transflective liquid crystal display and a method of manufacturing the same. The liquid crystal display includes a pair of substrates in which a plurality of pixels having a reflection region and a transmission region are defined, a color filter, formed on one of the substrates, having a stepped surface, a phase difference layer planarizing the stepped surface of the color filter and having a different phase differences for the reflection region and the transmission region, and a liquid crystal layer interposed between the pair of substrates.

  • Publication number: 20060007087
    Abstract: A semi-transmission liquid crystal display comprising a liquid crystal panel; a backlight unit to emit light to the liquid crystal panel; and a data driver to apply a data voltage to a data line of the liquid crystal panel; wherein, the liquid crystal panel comprises a TFT substrate which has a transmission area transmitting light from the backlight unit and a reflection area reflecting light from exterior, a color filter substrate which has color filter layer having a concave area which is formed corresponding to the transmission area, and a liquid crystal layer which is sandwiched between the TFT substrate and the color filter substrate and having varying thickness according to the concave area; and the data driver applies the data voltage to the data line in the liquid crystal panel by a transmission voltage mode when the backlight unit is on and by a reflection voltage mode when the backlight unit is off.
