An active matrix liquid crystal display having improved reliability. Pixel regions and a peripheral driver circuit are integrally packed on the display. TFTs forming the peripheral driver circuit are located inside a sealing material layer on the side of a liquid crystal material, thus protecting the peripheral driver circuit from external moisture and contaminants. This enhances the long-term reliability of the peripheral driver circuit. Pixel TFTs are arranged in pixel regions. The leads going from the TFTs forming the peripheral driver circuit to the pixel TFTs are shortened. This results in a reduction in the resistance. As a result, the display characteristics are improved.

There is provided a high quality liquid crystal panel having a thickness with high accuracy, which is designed, without using a particulate spacer, within a free range in accordance with characteristics of a used liquid crystal and a driving method, and is also provided a method of fabricating the same. The shape of a spacer for keeping a substrate interval constant is made such that it is a columnar shape, a radius R of curvature is 2 μm or less, a height H is 0.5 μm to 10 μm, a diameter is 20 μm or less, and an angle α is 65° to 115°. By doing so, it is possible to prevent the lowering of an opening rate and the lowering of light leakage due to orientation disturbance.

An object is to improve use efficiency of an evaporation material, to reduce manufacturing cost of a light-emitting device, and to reduce manufacturing time needed for a light-emitting device including a layer containing an organic compound. The pressure of a film formation chamber is reduced, a plate is rapidly heated by heat conduction or heat radiation by using a heat source, a material layer on a plate is vaporized in a short time to be evaporated to a substrate on which the material layer is to be formed (formation substrate), and then the material layer is formed on the formation substrate. The area of the plate that is heated rapidly is set to have the same size as the formation substrate and film formation on the formation substrate is completed by one application of heat.
