Liquid crystal display device

According to one embodiment, a liquid crystal display device including: a first substrate; a second substrate that is disposed so as to be opposed to the first substrate; a first wiring provided on the first substrate along a first direction; a second wiring provided along a second direction intersecting with the first direction; a thin-film transistor provided at an intersection between the first wiring and the second wiring; an organic insulating film formed on the thin-film transistor; a first opening that penetrates the organic insulating film; an island-shaped electrode that covers at least a part of an edge portion of a side surface portion and a bottom portion of the first opening; an inorganic insulating film that covers a common electrode and the island-shaped electrode; a second opening that penetrates the inorganic insulating film; and a pixel electrode formed on the inorganic insulating film and electrically connected to the island-shaped electrode through the second opening, wherein a bottom portion of the second opening is located at a position shifted from a bottom portion of the first opening in the direction of the second wiring.

In a liquid crystal display device, an upper electrode and a drain electrode are reliably connected to each other electrically, with preventing or suppressing an occurrence of an aperture ratio loss, or sufficiently reducing a parasitic capacitance between the scanning line and the lower electrode. An interlayer resin film is formed on a drain electrode, with a hole being formed on the interlayer resin film, and on the drain electrode exposed to a bottom portion of the hole, an island-shaped electrode is formed separately from a lower electrode. Moreover, on the island-shaped electrode, an inter-electrode insulating film is formed, a contact hole is formed in the inter-electrode insulating film, and an upper electrode is formed on the island-shaped electrode exposed to a bottom portion of the contact hole.

Liquid crystal display device and manufacturing method thereof and electronic device

A spacer portion for keeping a thickness of a liquid crystal layer is provided at an intersecting portion between a gate wiring and a source wiring when seen in a plan view, and a light shielding portion for spacer portion which shields the spacer portion from light is provided. The spacer portion is disposed in a region in which the light shielding portion for spacer portion is provided when seen in a plan view. Then, the source wiring has two bend portions which are bent in mutually different directions in the region in which the light shielding portion for spacer portion is provided when seen in a plan view.
