<p>A TFT is provided to transfer exactly a predetermined current to an organic light emissive layer and to improve the uniformity of brightness in each pixel by using a plurality of channel regions with uniform widths. A semiconductor layer and an insulating layer are formed on an insulating substrate. The semiconductor layer(7) is composed of first and second conductive regions(7b,7c) and a channel region(7a) between the first and the second conductive region. A gate electrode is formed on the insulating layer corresponding to the channel region. Source and drain electrodes(11,12) are connected to the first and the second conductive region. The channel region is composed of a plurality of portions. The width of each channel portion is in a predetermined range of 5 to 30 mum.</p> |
