摘要： In an organic EL panel having a device glass substrate provided with an organic EL element on a surface thereof, a sealing glass substrate attached to the device glass substrate and a desiccant layer formed on a surface of the sealing glass substrate, spacers are disposed between a cathode of the organic EL element and the desiccant layer. A heat-conductive layer can be formed on a surface of the sealing glass substrate including a pocket portion. The heat-conductive layer can be formed by vapor depositing or sputtering a metal layer such as a Cr layer or an Al layer. This inhibits damaging the organic EL element and increases a heat dissipating ability, thereby inhibiting deterioration of a device property caused by temperature rise.

摘要： A first contact hole is formed penetrating a gate insulating film, on which a gate electrode is formed and simultaneously a first contact is formed in the first contact hole. A second contact hole penetrating an interlayer insulating film is formed, and a second contact is formed in the second contact hole. A third contact hole is formed penetrating a planarization film, and an electrode is formed in the third contact hole. By using a plurality of contact holes for electrically connecting the electrode and a semiconductor film, the aspect ratio of each contact hole can be reduced, thereby achieving improvement in yield, high-level integration due to a reduction in difference in area between upper and bottom surfaces of the contact, and other advantageous improvements.

摘要： A device has a first transistor and a second transistor wherein a channel length direction of the first transistor extends along a first direction and a channel length direction of the second transistor extends along a second direction intersecting the first direction, and the second transistor is formed on a same substrate as the first transistor. A first channel region and a second channel region are formed in semiconductor layers which are simultaneously formed and a mobility of the semiconductor film has an anisotropy in the first and second directions. With this structure, transistors having different mobilities can be obtained while using the semiconductor films formed on the same substrate and from a same material. For example, it is possible to form a transistor in which a high resistance is required using a semiconductor layer of the same characteristics as that in a transistor in which a high speed operation is desired, on the same substrate and with a minimum area.

摘要： An inter-layer insulating film and a gate insulating film which are positioned on the optical path of light from an organic EL element to be externally emitted, for example, located under a transparent electrode, are removed. Because SiO2 films having a refractive index which differs significantly from refractive indexes of other films are used for these films, there was a problem of light attenuation in these layers. Such light attenuation can be reduced by removing these layers located in the region through which light from the organic EL element passes.

摘要： On a substrate, there is disposed a gate electrode having a section of a trapezoidal configuration expanded toward the substrate. The gate electrode is covered with a silicon nitride film having a thickness T1 of 400 Å, and a silicon oxide film having a thickness T2 of 1200 Åis formed on the silicon nitride film. A polycrystalline silicon film constructing an active region is formed on a gate insulating film constituted of the silicon nitride film and the silicon oxide film. By forming the silicon oxide film in a sufficient thickness of 1200 Åor more, and further forming the silicon nitride film 23 of 400 Åor more, a thin-film transistor cannot easily be influenced by a stepped portion formed by the gate electrode, and withstanding voltage of the gate insulating film of the thin-film transistor can be enhanced.

An orientation control window is formed in the common electrode. A distance Wp between adjacent pixel electrodes and/or a width Ws of the orientation control window is selected so as to satisfy Wp≧d/2 and/or Ws≧d/2, where d is a distance (or a cell gap) between the pixel electrodes and the common electrode. Viewing angle is widened and a viewing angle characteristic is improved, and abnormal orientation or grittiness of an image is eliminated.

摘要： A line beam is irradiated such that edge lines of the beam extend in a direction at an angle of 45° with respect to the vertical direction or the horizontal direction. As a result, a laser defective crystallization region R′ where the grain size has not become sufficiently large due to unevenness in intensity of the line beam passes at 45° across the carrier path connecting source and drain regions S and D to each other. The defective crystallization region R′ thus does not completely divide between the contact region CT, i.e., the carrier path between the source and drain regions. Therefore, a carrier path CP can be securely maintained without passing through the defective crystallization region R′, so that the ON-current is prevented from being reduced. Deterioration or unevenness in transistor characteristics caused by unevenness in intensity of laser irradiation can thus be prevented.
