摘要： A high-definition and high-contrast liquid crystal display device having a high aperture ratio without light leakage around a columnar spacer is provided. The liquid crystal display device of a horizontal electric field type includes a TFT substrate with a pixel electrode and a common electrode, a color filter substrate with a color filter, a columnar spacer interposed between the substrates, and a liquid crystal layer arranged between the substrates. A liquid crystal alignment film formed between the substrates is a photo-alignment film. The columnar spacer, formed on the color filter substrate or the TFT substrate, has a wall-like shape and an inclined surface extending in a direction parallel to or perpendicular to a direction in which the liquid crystal is initially aligned.

摘要： A display device includes a first substrate having organic and alignment films, a second substrate adhered to the first substrate by a sealant which surrounds a pixel region, a columnar spacer formed on the second substrate defining a distance between the first substrate and the second substrate, and a recessed portion formed in the organic film of the pixel region, the recessed portion facing to the columnar spacer. The recessed portion has a convex portion at a bottom of the recessed portion, and a height of a top of the convex portion from the first substrate is lower than a height of an upper surface of the organic film from the first substrate. A thickness of an alignment film on the convex portion is smaller than a thickness of the bottom of the recessed portion, and a top of the columnar spacer is in contact with the convex portion.

摘要： 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.
