Abstract: To provide a thin touch panel, a touch panel having a simple structure, a touch panel which can be easily incorporated into an electronic device, or a touch panel with a small number of components. The touch panel includes pixel electrodes arranged in a matrix, a plurality of signal lines, a plurality of scan lines, a plurality of first wirings extending in a direction parallel to the signal lines, and a plurality of second wirings extending in a direction parallel to the scan line. Part of the first wiring and part of the second wiring function as a pair of electrodes included in a touch sensor. The first wiring and the second wiring each have a stripe shape or form a mesh shape and are each provided between two adjacent pixel electrodes in a plan view.

Abstract: A display device having less defective alignment is provided. A display device having a high aperture ratio and including a capacitor which can increase charge capacity is also provided. A display device having a high aperture ratio, including a capacitor with large charge capacity, and having less defective alignment is also provided. A display device includes a pixel in a region defined by a scan line, a data line, and a capacitor line. The pixel includes a liquid crystal layer between a counter electrode and a pixel electrode, a spacer in the liquid crystal layer, and a transistor connected to the pixel electrode. The pixel electrode has a depressed portion, and alignment in the liquid crystal layer is controlled by the depressed portion and the spacer.

Abstract: A thin display device, a lightweight display device, or a bendable display device is provided. The display device can be fabricated by a method including a first step of forming a first electrode and a second electrode over a substrate such that they are apart from each other; a second step of sequentially forming a light-blocking layer over a support substrate, a resin layer covering the light-blocking layer, and a first coloring layer and a second coloring layer over the resin layer; a third step of bonding the substrate and the support substrate to each other with a liquid crystal layer containing liquid crystal, monomers, and a polymerization initiator positioned therebetween; a fourth step of performing light irradiation from the support substrate side so that the monomers in the liquid crystal layer are polymerized in a region not shielded by the light-blocking layer; and a fifth step of performing separation between the resin layer and each of the support substrate and the light-blocking layer to remove the support substrate and the light-blocking layer.
