Abstract: A liquid crystal display device includes a liquid crystal panel (2) disposed between two linear polarization plates (1, 3) and a triacetyl cellulose film having biaxial optical anisotropy (4), the triacetyl cellulose film having biaxial optical anisotropy (4) (i) being disposed further from the screen front side than a front polarization plate, which is one of the two linear polarization plates (1, 3), and (ii) having a planar retardation comprised in a range from 40 nm to 100 nm. Accordingly, it is possible to provide a liquid crystal display device allowing an observer to perceive, through polarized sunglasses and with a high display quality, an image on a screen not only from a frontal viewpoint but also if an azimuth angle and a polar angle at which viewpoints are set are shifted from the frontal viewpoint.

Abstract: A transfiective liquid crystal display panel, in which at least one of a pixel electrode substrate and a counter electrode substrate is provided with a protruding portion so that the thickness of a liquid crystal layer in a reflective region is smaller than that in a transmissive region, wherein a light-blocking section for shading a defective orientation domain formed by an insufficiently-rubbed portion around the protruding portion is formed simultaneously with, and using the same material as, another element such as a storage capacitor electrode section, a signal line or a scanning line. Thus, the decrease in the display quality due to the defective orientation domain can be suppressed without adding to the production process.

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.

Abstract: A liquid crystal display device of the present invention includes: a first substrate; a second substrate; a liquid crystal layer provided between the first substrate and the second substrate; and a plurality of picture element regions for displaying an image. Each of the plurality of picture element regions includes a transmission region in which an image is displayed in a transmission mode by using light that is coming from the side of the first substrate, and a reflection region in which an image is displayed in a reflection mode by using light that is coming from the side of the second substrate. The height of a surface of the second substrate on the side closer to the liquid crystal layer in the reflection region is greater than that in the transmission region, while the height of a surface of the first substrate on the side closer to the liquid crystal layer in the reflection region is substantially equal to that in the transmission region.

Abstract: In the liquid crystal display device of the present invention, a filter of, for example, red, green, or blue is formed on a glass substrate surface of a liquid crystal layer side, and if necessary, a black mask is formed between the filters. The filter has a first region and a second region with a film thickness thinner than that of the first region. The second region has, on the inside, an uncolored region where the filter is not formed. In one pixel region, the first region is formed so as to correspond to a transmissive region and the second region and the uncolored region are formed so as to correspond to a reflective region. A reflective electrode and a transparent electrode are formed on another glass substrate surface of the liquid crystal layer side.
