In the display device, a transistor used for a transmissive liquid crystal display element, the transmissive liquid crystal display element, a transistor used for a reflective liquid crystal display element, and the reflective liquid crystal display element are stacked in this order between a pair of substrates. In a manufacturing process, one or two manufacturing substrates are used in addition to the pair of substrates included in the display device. The display device is manufactured in such a manner that a second liquid crystal and a second sealant provided to surround the second liquid crystal are bonded to a first liquid crystal sealed using a first sealant. The bonding process is performed such that the first sealant and the second sealant overlap with each other. Moreover, an end portion of the first sealant which is in contact with the first liquid crystal is substantially aligned with or positioned closer to the inner side of the display device than an end portion of the second sealant which is in contact with the second liquid crystal.

Abstract: A semiconductor layer of a transistor is formed of an oxide semiconductor film including a crystal part. An organic resin film covering the transistor is formed. By treatment such as drying treatment on the organic resin film in a cell process, variations in the threshold voltage of the oxide semiconductor transistor due to moisture can be suppressed. A common electrode faces a pixel electrode. The common electrode and the pixel electrode are formed over the organic resin film with an insulating film provided therebetween. Therefore, a capacitor can be provided to a liquid crystal element if a pixel does not include a wiring for a storage capacitor. An antistatic electrode is provided on the outer side of a color filter substrate and the capacitance between the antistatic electrode and the common electrode is utilized, so that the liquid crystal display device can be used as a touch panel.
