Abstract: To provide a display device with excellent display quality, in a display device including a signal line, a scan line, a transistor, a pixel electrode, and a common electrode in a pixel, the common electrode is included in which an extending direction of a region overlapping with the signal line differs from an extending direction of a region overlapping with the pixel electrode in a planar shape and the extending directions intersect with each other between the signal line and the pixel electrode. Thus, a change in transmittance of the pixel can be suppressed; accordingly, flickers can be reduced.

Abstract: A display device that is suitable for high definition and a method for manufacturing thereof are provided. The display device includes a reflective liquid crystal element. A liquid crystal layer has a first portion overlapping with a reflective electrode that reflects visible light and blocks ultraviolet light, and a second portion overlapping with a region between two adjacent reflective electrodes. The first portion contains a monomer and liquid crystal and the second portion contains a polymer obtained by polymerization of the monomer. In the second portion, the polymer constitutes the framework of a columnar partition wall which bonds a pair of substrates to each other. The partition wall can be formed in a self-aligned manner by using the reflective electrode as a light-blocking mask at the irradiation with light. The polymer is positioned to fit a depression portion of an insulating layer over which the reflective electrode is provided.
