    Abstract: In an LCD device, the slope angle of a wall surface of a wall structure (wall-surface slope angle) is varied in accordance with the angle formed between the wall structure and an alignment treatment direction (alignment treatment angle). At places where the alignment treatment angle is small, the wall-surface slope angle is made larger; conversely, at places where the alignment treatment angle is large, the wall-surface slope angle is made smaller.

    Abstract: In an LCD device having wall electrodes, four kinds of pixels are used that impart different alignment properties to the liquid crystal molecules. Specifically, the LC molecules are aligned such that: the LC molecules in first pixels twist clockwise and rise in a plus direction; the LC molecules in second pixels twist clockwise and rise in a minus direction; the LC molecules in third pixels twist counterclockwise and rise in the plus direction; and the LC molecules in fourth pixels twist counterclockwise and rise in the minus direction. The pixels of the same type are arranged in rows such that their long sides are adjacent to one another.

    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%.
