    • A display panel (100) is provided which allows optimization of the respective characteristics of different semiconductor elements without incurring an increase in manufacturing cost. The display panel (100) includes: pixel TFTs (11) disposed in a display section (101); scanning driver TFTs (12) disposed in a scanning driver (102); and data driver (13) disposed in a data driver (103). A polysilicon film of the pixel TFTs (11), the scanning driver TFTs (12), and the data driver TFTs (13) is polycrystallized by irradiation of laser light so as to have a crystal growth direction that goes along a scanning direction of the laser light. The pixel TFTs (11) are disposed so that the crystal growth direction of the polysilicon film is substantially perpendicular to the directions of current paths of the pixel TFTs (11). The scanning driver TFTs (12) and the data driver TFTs (13) are so that the crystal growth direction of the polysilicon film is substantially parallel to the directions of current paths of the scanning driver TFTs (12) and the data driver TFTs (13).
    • 提供了显示面板(100),其允许优化不同半导体元件的相应特性,而不会导致制造成本的增加。 显示面板(100)包括:设置在显示部(101)中的像素TFT(11); 设置在扫描驱动器(102)中的扫描驱动TFT(12); 和数据驱动器(13),其设置在数据驱动器(103)中。 像素TFT(11),扫描驱动器TFT(12)和数据驱动器TFT(13)的多晶硅膜通过激光的照射被多晶化,以具有沿着扫描方向的晶体生长方向 激光灯。 像素TFT(11)被布置成使得多晶硅膜的晶体生长方向基本上垂直于像素TFT(11)的电流路径的方向。 扫描驱动器TFT(12)和数据驱动器TFT(13)使得多晶硅膜的晶体生长方向基本上平行于扫描驱动TFT(12)和数据驱动器TFT(13)的电流路径的方向 )。
