  • Patent number: 7471346
    Abstract: A transflective type liquid crystal display panel used as a displaying liquid crystal panel in a 2D/3D switching type liquid crystal panel, wherein a color filter having a colored layer and a transparent layer is provided on an opposing substrate. The transparent layer is formed to face only the reflective region of an active matrix substrate (region where a reflective electrode is formed), and serves as a diffuser processed layer. Accordingly, a liquid crystal display panel having a 2D/3D switching function and a transflective function can prevent moire in 2D display and at the same time provide good 3D display.
    Type: Grant

  • Patent number: 7006182
    Abstract: In a transmission/reflection combination type LCD that includes a CF substrate having a counter electrode part; a TFT substrate having a reflection pixel electrode part and a transmission pixel electrode part and disposed to oppose the CF substrate; and a liquid crystal layer interposed between these substrates, each pixel has a reflection region and a transmission region, and includes a convex for making the thickness of the liquid crystal layer smaller in the reflection region than in the transmission region. The convex is provided not on the TFT substrate but on the CF substrate, so that the downstream end of the convex can be disposed in a position shifted toward the upstream side along the rubbing direction relatively to the reflection pixel electrode part disposed on the TFT substrate.

  • Publication number: 20050062918
    Abstract: A liquid crystal display device of the present invention includes: a liquid crystal layer; a first substrate and a second substrate opposing each other with the liquid crystal layer being interposed therebetween; a reflection layer provided on one side of the liquid crystal layer that is closer to the first substrate; a polarizer provided on one side of the liquid crystal layer that is closer to the second substrate; a phase compensator provided between the liquid crystal layer and the polarizer and having a slow axis within a plane parallel to the liquid crystal layer; and at least a pair of electrodes for applying a voltage across the liquid crystal layer.
