摘要:
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.

An integrated circuit using conductive interconnects made of aluminum or a material consisting chiefly of aluminum. Defects due to hillocks and whiskers are prevented. The integrated circuit is composed of TFTs. Gate interconnects are made of aluminum. Before a metallization film for forming the gate interconnects is patterned, slits are formed in locations where crosstalks and shorts are likely to occur by generation of hillocks and whiskers. The surfaces inside the slits are anodized. The conductive interconnects are formed, using the locations provided with the slits. In this way, during the anodization, unwanted stress is prevented. Furthermore, it is unlikely that a required electric current cannot be supplied for the anodization because of excessive complexity of the interconnection pattern.

摘要:
An object of the present invention is to provide an EL display device, which has a high operating performance and reliability.A third passivation film 45 is disposed under an EL element 203 which comprises a pixel electrode (anode) 46, an EL layer 47 and a cathode 48, to make a structure in which heat generated by the EL element 203 is radiated. Further, the third passivation film 45 prevents alkali metals within the EL element 203 from diffusing into the TFTs side, and prevents moisture and oxygen of the TFTs side from penetrating into the EL element 203. More preferably, heat radiating effect is given to a fourth passivation film 50 to make the EL element 203 to be enclosed by heat radiating layers.

An object of the present invention is to provide an EL display device having a high operation performance and reliability. The switching TFT 201 formed within a pixel has a multi-gate structure, which is a structure which imposes an importance on reduction of OFF current value. Further, the current control TFT 202 has a channel width wider than that of the switching TFT to make a structure appropriate for flowing electric current. Morever, the LDD region 33 of the current control TFT 202 is formed so as to overlap a portion of the gate electrode 35 to make a structure which imposes importance on prevention of hot carrier injection and reduction of OFF current value.

There is provided an electronic device having high reliability and high color reproducibility. A pixel structure is made such that a switching FET (201) and an electric current controlling FET (202) are formed on a single crystal semiconductor substrate (11), and an EL element (203) is electrically connected to the electric current controlling FET (202). The fluctuation in characteristics of the electric current controlling FET (202) is very low among pixels, and an image with high color reproducibility can be obtained. By taking hot carrier measures in the electric current controlling FET (202), the electronic device having high reliability can be obtained.
