說(shuō)明書(shū)

Another embodiment of the present invention is a display device including the light-emitting element having any of the above structures, and at least one of a color filter and a transistor. Another embodiment of the present invention is an electronic device including the display device, and at least one of a housing and a touch sensor. Another embodiment of the present invention is a lighting device including the light-emitting element having any of the above-described structures, and at least one of a housing and a touch sensor. The category of one embodiment of the present invention includes not only a light-emitting device including a light-emitting element but also an electronic device including a light-emitting device. Accordingly, a light-emitting device in this specification refers to an image display device or a light source (including a lighting device). A display module in which a connector such as a flexible printed circuit (FPC) or a tape carrier package (TCP) is connected to a light-emitting element, a display module in which a printed wiring board is provided on the tip of a TCP, and a display module in which an integrated circuit (IC) is directly mounted on a light-emitting element by a chip on glass (COG) method are also embodiments of the present invention.
