Light-Emitting Device and Display Device

[0029]In this embodiment, one embodiment of an EL display device will be described with reference to FIGS. 1A and 1B, FIGS. 2A, 2B1, 2B2, and 2B3, and FIGS. 3A to 3C.

[0030]FIG. 1A is a cross-sectional view of a display portion in a display device of this embodiment. FIGS. 1B1 and 1B2 are enlarged views of part of the cross-sectional view of FIG. 1A.

[0031]The display device illustrated in FIG. 1A includes a first pixel 130a and a second pixel 130b. The first pixel 130a includes a first light-emitting element 132a provided over a substrate 100 and a first color filter layer 134a provided for a counter substrate 128 in a region overlapping with the first light-emitting element 132a. The second pixel 130b includes a second light-emitting element 132b provided over the substrate 100 and a second color filter layer 134b provided for the counter substrate 128 in a region overlapping with the second light-emitting element 132b.

[0032]In the display device illustrated in FIG. 1A, the first colo

[0148]In this embodiment, an active matrix display device that is one embodiment of the present invention will be described with reference to FIGS. 4A and 4B. FIG. 4A is a plan view illustrating a display device. FIG. 4B is a cross-sectional view taken along line A-B and C-D in FIG. 4A

[0149]In the display device illustrated in FIGS. 4A and 4B, an element substrate 410 and a sealing substrate 404 are attached to each other with a sealant 405, and a driver circuit portion (a source-side driver circuit 401 and a gate side driver circuit 403) and a pixel port including a plurality of pixels are provided.

[0150]Note that a wiring 408 is a wiring for transmitting signals that are to be inputted to the source side driver circuit 401 and the gate side driver circuit 403, and receives a video signal, a clock signal, a start signal, a reset signal, and the like from a flexible printed circuit (FPC) 409 which serves as an external input terminal. Although only the FPC is illustrated here, a printe

[0184]A display device disclosed in this specification can be applied to a variety of electronic appliances (including game machines). Examples of electronic devices include a television set (also referred to as a television or a television receiver), a monitor of a computer or the like, a camera such as a digital camera or a digital video camera, a digital photo frame, a mobile phone handset (also referred to as a mobile phone or a mobile phone device), a portable game console, a portable information terminal, an audio reproducing device, and a large-sized game machine such as a pachinko machine.

[0185]FIG. 5A illustrates a laptop personal computer, which includes a main body 3001, a housing 3002, a display port, a keyboard 3004, and the like. By applying the display device described in Embodiment 1 or 2 to the display port, the laptop personal computer can have a high level of definition and consumes a small amount of power.
