摘要： An active matrix display device comprising an integrated peripheral driver circuit improved in image quality, provided in such a constitution that the feed through voltage &Dgr;Vs is set lower than the voltage Vgr necessary for realizing a single gradation. In this manner, a stable gradation display is obtained without being influenced by the feed through voltage &Dgr;Vs even when the fluctuation in the characteristics of the thin-film transistors provided in active matrix circuit may fluctuate the &Dgr;Vs.

摘要： In a laser irradiation apparatus having low running costs as compared with a conventional apparatus and a laser beam irradiation method using the same, a crystalline semiconductor film having a crystal grain of a grain size equivalent to or larger than a conventional one is formed, and a TFT is manufactured by using the crystalline semiconductor film, so that the TFT enabling a high speed operation is realized. In a case where a laser beam of a short output time from a solid laser as a light source is irradiated to a semiconductor film, another laser beam is delayed from one laser beam, and the laser beams are synthesized to be irradiated to the semiconductor film, so that a cooling speed of the semiconductor film is made gentle, and it becomes possible to form the crystalline semiconductor film having the crystal grain of the grain size equivalent to or larger than that in a case where a laser beam having a long output time is irradiated to the semiconductor film. By manufacturing a TFT using such a crystalline semiconductor film, the TFT enabling the high speed operation can be realized.

摘要： Protrusions called ridges are formed on the surface of a crystalline semiconductor film formed by a laser crystallization method or the like. A heat absorbing layer are formed below a semiconductor film. When the semiconductor film is crystallized by laser, a temperature difference is produced between a semiconductor film 1010 positioned above a heat absorbing layer 1011 and a semiconductor film 1013 of the other region to produce a difference in thermal expansion at the boundary of the outside end 1015 of the heat absorbing layer. This difference produces a strain to form a surface wave. The surface wave starting at the outer periphery of the heat absorbing layer is formed in the vicinity of the heat absorbing layer. When the semiconductor layer is solidified after it is melted, the protrusions of the surface wave remain as protrusions after the semiconductor film is solidified.

摘要： A method of fabricating a driver circuit for use with a passive matrix or active matrix electrooptical display device such as a liquid crystal display. The driver circuit occupies less space than heretofore. A circuit (stick crystal) having a length substantially equal to the length of one side of the matrix of the display device is used as the driver circuit. The circuit is bonded to one substrate of the display device, and then the terminals of the circuit are connected with the terminals of the display device. Subsequently, the substrate of the driver circuit is removed. This makes the configuration of the circuit much simpler than the configuration of the circuit heretofore required by the TAB method or COG method, because conducting lines are not laid in a complex manner. The driver circuit can be formed on a large-area substrate such as a glass substrate. The display device can be formed on a lightweight material having a high shock resistance such as a plastic substrate. Hence, a display device having excellent portability can be obtained.
