Abstract
A high-image-quality display device having a transmissive mode and a reflective mode is provided. Furthermore, the display device is manufactured with higher yield and higher productivity. 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.
