Abstract: A semiconductor device includes TFTs designed in accordance with characteristics of circuits. In a first structure of the invention, the TFT is formed by using a crystalline silicon film made of a unique crystal structure body. The crystal structure body has a structure in which rod-like or flattened rod-like crystals grow in a direction parallel to each other. In a second structure of the invention, growth distances of lateral growth regions are made different from each other in accordance with channel lengths, of the TFTs. By this, characteristics of TFTs formed in one lateral growth region can be made as uniform as possible.

Abstract: It is an object of the present invention to provide a technology for manufacturing a highly reliable display device at a low cost with high yield. In the present invention, a spacer is formed over a pixel electrode, thereby protecting the pixel electrode layer from a mask in formation of an electroluminescent layer. In addition, since a layer that includes an organic material that has water permeability is sealed in a display device with a sealing material and the sealing material and the layer that includes the organic material are not in contact, deterioration of a light-emitting element due to a contaminant such as water can be prevented. The sealing material is formed in a portion of a driver circuit region in the display device, and thus, the narrower frame margin of the display device can also be accomplished.
