Abstract: A liquid crystal display device includes: a drive element substrate having plural interlayer insulating films laminated thereon, and having a non-opening area in which signal lines and a transistor are provided and an opening area in which none of the signal lines and the transistors is provided in the plural interlayer insulating films; and a counter substrate provided so as to face the drive element substrate through a liquid crystal, in which the drive element substrate includes: an insulating portion which is provided in the interlayer insulating film(s) between the non-opening area and the opening area, and whose refractive index is different from that of (each of) the interlayer insulating film(s); and a light blocking film provided between the insulating portion and the counter substrate.

Abstract: A liquid crystal display device includes an active matrix substrate and a counter substrate opposing each other with a gap therebetween defined by a plurality of columnar spacers. The active matrix substrate has a plurality of spacer holes each receiving therein a corresponding one of the columnar spacers, and a plurality of dummy spacer holes aligned with the spacer holes and each receiving therein no columnar spacer.

Abstract: A data wiring is provided on a glass substrate in an active element substrate. For the data wiring, a first portion, extending in a direction that slopes and forms a fixed angle with respect to the rubbing direction of an oriented film, and a second portion, extending in a direction sloping to the opposite side of the first portion are alternately arranged and formed in a zigzag pattern. A convex insulation film is formed in a zigzag pattern to cover the data wiring and a common electrode is formed in a zigzag pattern to cover the insulation film. A shilding layer is formed in a zigzag pattern on an opposing substrate to completely cover the insulation film and does not protrude from the region directly above the common electrode. The high-contrast, multi-domain system in-plane switching type liquid crystal display device obtained with a high numerical aperture and low black brightness.

Abstract: First and second columnar spacers are formed on a color filter substrate, and step films are formed on an active matrix substrate in the same step as signal lines. The columnar spacers are formed by proximity exposure, and the step films are formed by being exposed by a lens projection system. In plan view, the step films are disposed inside the columnar spacers. The first columnar spacers are made to be in contact with the regions of the protective film that are higher in elevation with the step films in the active matrix substrate.

Abstract: A sealing member is formed on a glass substrate, and dropping points are arranged in the form of a matrix in the region surrounded by the sealing member. The dropping points arranged in the outermost columns and the second outermost columns are connected respectively to imagine first straight lines and second straight lines. Third straight lines are imagined to be equidistant from the first straight lines and the second straight lines. The positions of the dropping points are determined in such a manner that the density of the dropping points in four edge divided regions can be 0.9 to 1.1 times the density of the dropping points in the region as a whole, and the density of the dropping points in four corner divided regions can be 0.83 to 1.17 times the density of the dropping points in the region as a whole.

Abstract: Spacer heights are measured at a plurality of measuring points on the display area in a substrate, and the distribution of spacer heights in the display area is estimated in accordance with the measured spacer heights. The average value of spacer heights are calculated by virtually dividing the display area into a plurality of sectors, and a dispensing amount in each sector is accurately controlled in accordance with the difference between the average value and a reference value.

Abstract: A data wiring is provided on a glass substrate in an active element substrate. For the data wiring, a first portion, extending in a direction that slopes and forms a fixed angle with respect to the rubbing direction of an oriented film, and a second portion, extending in a direction sloping to the opposite side of the first portion are alternately arranged and formed in a zigzag pattern. Furthermore, a convex insulation film is formed in a zigzag pattern so as to cover the data wiring and a common electrode is formed in a zigzag pattern so as to cover the insulation film. Additionally, the shielding layer is formed in a zigzag pattern on an opposing substrate such that it completely covers the insulation film and does not protrude from the region directly above the common electrode. Because of this, a high-contrast, multi-domain system in-plane switching type liquid crystal display device can be obtained with a high numerical aperture and low black brightness.
