    Abstract: A liquid crystal display device comprising a TFT substrate having pixels each including a common electrode formed on an organic passivation film, an interlayer insulating film formed so as to cover the common electrode, a pixel electrode having a slit and formed on the interlayer insulating film, a through-hole formed in the organic passivation film and the interlayer insulating film, and a source electrode electrically conducted to the pixel electrode via the through-hole. A taper angle at a depth of D/2 of the through-hole is equal to or more than 50 degrees. The pixel electrode covers part of a side wall of the through-hole but does not cover the remaining part of the side wall of the through-hole. This configuration facilitates the alignment film material to flow into the through-hole, thereby solving a thickness unevenness of the alignment film in vicinity of the through-hole.

    Abstract: In an IPS mode liquid crystal display device, an interlayer insulating film is formed on a common electrode formed in a planar shape, and a pixel electrode is formed on the interlayer insulating film. The distance between the TFT substrate and the counter substrate is determined by a columnar spaces. The pixel electrode includes one comb-shaped electrode and a contact part. The tip of the comb-shaped, electrode overlaps the columnar spacer as seen in a plan view. The columnar spacer is present in, the area in which an electric field that allows the liquid crystal molecules to rotate backward occurs when a voltage is applied to the pixel electrode, so that the reverse rotation of the liquid crystal molecules does not occur, and it is possible to prevent the domain from occurring.

    Abstract: Detection electrode wirings formed by an ITO film have a high resistance and the detection capability thereof is degraded with the increase of the size and/or resolution. A manufacturing method of a display device includes: (a) arranging liquid crystal between an array substrate and a counter substrate; (b) forming a metal layer and a low-reflection layer on the counter substrate after the step (a); (c) applying an overcoat film onto the metal layer and the low-reflection layer; and (d) curing the overcoat film to form a protection layer. The step (d) cures the overcoat film with light and heat.

    Abstract: Provided is a liquid crystal display panel in which both the prevention of low-temperature bubble defects and the prevention of unevenness in brightness by pressure can be achieved without the need of forming multiple types of spacers differing in the height. In a liquid crystal display panel comprising a plurality of spacers 14 arranged between a pair of transparent substrates 11 and 12 and a liquid crystal 13 encapsulated between the transparent substrates, the spacers 14 are of a uniform height and each spacer 14 is substantially in a trapezoidal shape in which the ratio between the top area and the bottom area is 0.3 or less. The spacers 14 are formed on one of the transparent substrates 11 and 12. The spacers 14 are arranged at appropriate density so that the contact area ratio of the spacers' top surfaces in contact with the opposing substrate per unit area is within a range of 0.8%-1.0%.
