    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: Various layer separation states are generated by the combination of a polyamide acid ester and a polyamide acid and a long residual image characteristic cannot be further improved merely by combining them. A liquid crystal display device comprises a substrate, a liquid crystal layer, and an orientation film placed between the substrate and the liquid crystal layer. The orientation film comprises a polyimide precursor having two or more components. In the polyimide precursor, an octanol-water partition coefficient is defined as log P and the difference in log P (Δ log P) between the two components having most distant log Ps is set so as to fall within a prescribed range.

    Abstract: According to one embodiment, a liquid crystal display panel includes a first substrate, a second substrate, a sealant and a liquid crystal layer. The first substrate includes a switching element and a pixel electrode. The second substrate includes a first organic insulating film in which a first trench portion is formed, a projection formed beneath the first organic insulating film, and a first barrier layer. The first barrier layer is formed continuously from an inside of the first trench portion to under the projection.
