摘要： For obtaining p-Si by irradiating a laser beam to an a-Si layer to polycrystallize, an energy level in a region to be irradiated by the laser beam is set such that a level at the rear area of the region along a scan direction of the laser beam is lower than that at the front area or the center area of the region. The energy level at the front area or the center area of the region is set such that it is substantially equal to or more than the upper limit energy level which maximizes a grain size of the p-Si obtained. Since an energy profile is set as described above, when the laser beam is scanned on the a-Si layer, an irradiated energy of the laser on the region is gradually lowered from the upper limit as the laser beam passes through, which allows the semiconductor layer to be annealed within an optimal energy level during the latter half of the annealing process.
摘要翻译：为了通过将激光束照射到a-Si层进行多晶化来获得p-Si，将由激光束照射的区域中的能级设定为使沿着扫描方向的区域的后部区域的电平激光束比区域前区域或中心区域低。该区域的前部区域或中心区域的能级被设定为使得所获得的p-Si的粒径最大化的上限能级基本上等于或大于该能级。由于如上所述设定能量分布，当在a-Si层上扫描激光束时，该区域上的激光的照射能量随着激光束通过而从上限逐渐降低，这允许半导体在退火过程的后半期间在最佳能级内退火的层。

摘要： An organic EL element with an emissive layer and a second electrode layer is formed on a device glass substrate in an organic EL display device. The second electrode layer covers the emissive layer. An anti-reflection layer for preventing the reflection of light by the second electrode layer is formed on the device glass substrate except the region where the emissive layer is formed. Since this layer prevents the reflection of light by the second electrode layer, only the light from the emissive layer radiates outwards through the device glass substrate, improving the contrast of the organic EL display device.

摘要： In a bottom gate-type thin-film transistor manufacturing method, after ion doping, an ion stopper (55) is removed. The ion stopper (55) does not remain in the interlayer insulating film (8) lying immediately above the gate electrode. The thin-film transistor has such a structure that no ion stopper (55), and the interlayer insulating layer is in direct contact with at least the channel region of the semiconductor layer (4). The impurity concentration in the vicinity of the interface between the interlayer insulating film and the semiconductor layer 4 is 1018 atoms/cc or less. This structure can prevent the back channel phenomenon and reduce variations in characteristic resulting from variations in manufacturing.

摘要： The display device of this invention, in which the retaining circuit for retaining the image signal is provided for each of the pixel elements, is capable of operating under two operation modes, a normal operation mode and a memory mode. Since the placement of the retaining circuit 110, which requires relatively large area, is confined to the area for the pixel element electrode 17 not in between the neighboring pixel element electrodes 17, the required area for one pixel element is minimized, resulting in the size reduction of the liquid crystal display device. By placing at least a portion of the retaining circuit in the area of the pixel element electrode 17 of the neighboring pixel element, the detour of the wiring can be omitted, resulting in the efficient use of the space. By this, the area required for the retaining circuit is minimized, directly resulting in the reduction of the size of the liquid crystal display device.

摘要： A first moisture blocking layer formed of a silicon type nitride film such as SiNx or the like is formed over the entire surface so as to cover a drain electrode and a source electrode of a TFT. On the first moisture blocking layer, a first planarization film formed of an organic material is provided. On the first planarization film, a second moisture blocking layer formed of SiNx or the like is provided. In the peripheral region, the second moisture blocking layer extends down on the first moisture blocking layer and is connected with the first moisture blocking layer. Also, a sealing glass is bonded to the second moisture blocking layer using the sealing member. By enclosing the first planarization film by the first moisture blocking layer and the second moisture blocking layer, intrusion of external moisture can be effectively prevented.

摘要： An organic EL display device comprises a first TFT (30), which is a switching TFT, an organic EL element driving TFT, and an organic EL element (60) having an anode (61), a cathode (66), and an emissive element layer (65) interposed between both electrodes. The EL element driving TFT comprises a second and third TFTs (35, 40) connected in parallel. Because electrical current to the organic EL element (60) is supplied from a plurality of TFTs (35, 40), variation in the total current value can be suppressed to therefore reduce the variation in luminance, even when characteristics vary among the TFTs driving the organic EL element.
