The invention provides a display device and a method for manufacturing the display device. The display device is equipped with: a pixel having a first thin film transistor; and a drive circuit, whichhas a second thin film transistor, and which drives the pixel. The display device is configured such that a first channel region relating to the first thin film transistor, and a second channel regionrelating to the second thin film transistor have different electrical characteristics (for instance, electron mobilities), respectively, thereby enabling the first thin film transistor and the secondthin film transistor to suitably operate for respective roles. 本发明提供显示装置和该显示装置的制造方法，该显示装置具有：具有第1薄膜晶体管的像素；具有第2薄膜晶体管、驱动上述像素的驱动电路，通过以上述第1薄膜晶体管涉及的第1沟道区域和上述第2薄膜晶体管涉及的第2沟道区域的电特性(例如电子迁移率)不同的方式构成该显示装置，从而第1薄膜晶体管和第2薄膜晶体管能够适于各自职能地工作。
