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.

Transflective liquid crystal display panel, 2D/3D switching type liquid crystal display panel, and 2D/3D switching type liquid crystal display

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. Accordingly, lowering of display quality in the transmission region due to a domain formed in a region of the liquid crystal layer correspondingly to a shade portion shaded from the rubbing processing with the convex can be suppressed without sacrificing the numerical aperture of the transmission region.
