摘要:
Provided is an image display device comprising, on a TFT substrate: a plurality of gate lines and a plurality of drain lines which intersect with each other; a pixel TFT provided within a pixel which is enclosed by a pair of adjacent gate lines and a pair of adjacent drain lines; a gate driver TFT which is connected to one of the plurality of gate lines to drive the one of the plurality of gate lines, wherein the pixel TFT and the gate driver TFT each include an amorphous semiconductor film as a channel, wherein the pixel TFT has a bottom gate structure, wherein the gate driver TFT has a dual gate structure, and wherein a mobility on a top surface side of the semiconductor film of the gate driver TFT is higher than a mobility on a top surface side of the semiconductor film of the pixel TFT.
