  • Publication number: 20060038944
    Abstract: A display apparatus includes a voltage applying unit formed on a base substrate. An organic layer having a plurality of micro lens parts is formed to expose an output terminal of the voltage applying unit. Each of the micro lens parts has an irregular shape of a different size to increase a light reflectance. A pixel electrode comprises a first electrode formed on the organic layer and a second electrode formed on an upper face of the first electrode. The second electrode has a light transmitting window partially formed on the second electrode. A second substrate comprises a common electrode corresponding to the pixel electrode. A liquid crystal layer is disposed between the first and second substrates. The display apparatus may improve a display quality by increasing an amount of a light reflected from the pixel electrode.

  • Publication number: 20050179840
    Abstract: A color filer panel includes a first substrate, a light reflecting member, a color filter, and a light polarizing layer. The light reflecting member is formed on the first substrate. The light reflecting member reflects at least a portion of an external light. The color filter is formed on the light reflecting member. The light polarizing layer is formed over the color filter. Advantageously the time for manufacturing the color filter panel is reduced. Furthermore, a misalignment between the first substrate and the light reflecting member or between the first substrate and the light polarizing layer, which occurs when the light reflecting member or the light polarizing layer is formed in a plate type, is reduced to enhance productivity. Additionally, the light before and after being reflected by the light reflecting member has substantially the same color to enhance display quality.

  • Publication number: 20050146658
    Abstract: A substrate for a display apparatus includes a plate, a switching element, an insulating layer, and a partition wall. The plate has a reflection region on which a light that is provided from an exterior to the substrate is reflected and a transmission region through which a light generated from a backlight assembly passes. The switching element is on the plate. The insulating layer is on the plate having the switching element. The transmission region of the insulating layer is recessed when compared to the reflection region of the insulating layer. The insulating layer has a contact hole through which a first electrode of the switching element is partially exposed. The partition wall divides the transmission region into a plurality of transmission portions. Advantageously, an image display quality of the display apparatus is improved, and manufacturing cost is decreased.

  • Publication number: 20050134773
    Abstract: An LCD apparatus including a first member, a second member, a liquid crystal layer and an optical film assembly is presented. A phase delay of the optical film assembly is about ??. In a normally white mode, the phase delay of the liquid crystal layer is about (?/2)+? when no voltage is applied and about “?” when voltage is applied. In a normally black mode, the phase delay of the liquid crystal layer is about “?” when no voltage is applied, and about (?/2)+? when voltage is applied. The phase delay between the liquid crystal layer when voltage is applied and the liquid crystal layer when voltage is not applied is about ?/2. “?” is a positive number. By manipulating the value of ?, power consumption can be reduced. For example, the apparatus can be driven with a voltage below 2.5 V.
