Dimming panel, dimming unit, and liquid crystal display device

An active matrix substrate of a display device of the present invention includes a glass substrate (), a plurality of connection terminals () formed on the surface of the glass substrate and arranged in parallel with one another at an equal interval, and an interlayer insulating film () covering the plurality of connection terminals. The edge of the interlayer insulating film is so formed that tips of the plurality of connection terminals are exposed. An opening () is formed along the edge of the interlayer insulating film between two adjacent connection terminals. It is possible to avoid formation of pixel electrode material residue near the edge of the interlayer insulating film when a pixel electrode is formed by photo-etching through the formation of a pixel electrode material layer and a photosensitive resist layer on the interlayer insulating film.

Display device and manufacturing method therefor

A photomask of the present invention is a photomask for use in production of a display device, the photomask having on its surface a plurality of drawn areas and a transitional portion between two adjacent ones of the drawn areas. A pattern is formed on at least one of the drawn areas. A ratio between a pattern pitch and a transitional portion pitch is an integral ratio such that a length defined by a least common multiple of the pattern pitch and the transitional portion pitch is 1 mm or less.
