Abstract: In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.

Abstract: A device includes a substrate, an alignment structure disposed on the substrate, and a layer of a birefringent medium disposed on the alignment structure. The birefringent medium has an extraordinary refractive index, an ordinary refractive index different from the extraordinary refractive index, and an intermediate refractive index between the extraordinary refractive index and the ordinary refractive index. Molecules of the birefringent medium are configured to form helical structures having a helical axis. The layer is configured with an out-of-plane principal refractive index along the helical axis, and two equal in-plane principal refractive indices within a plane perpendicular to the helical axis. The out-of-plane principal refractive index is equal to the intermediate refractive index, and is substantially the same as the two equal in-plane principal refractive indices.
