Abstract:
1. An electrophoretic display device comprising: a gate electrode over a first flexible substrate; a gate insulating film over the gate electrode; a microcrystalline semiconductor film over the gate insulating film; an amorphous semiconductor film over the microcrystalline semiconductor film; source and drain regions over the amorphous semiconductor film; source and drain electrodes over the source and drain regions; an interlayer insulating film over the source and drain electrodes; a pixel electrode over the interlayer insulating film, the pixel electrode electrically connected with one of the source and drain electrodes; an electrophoretic display element over the pixel electrode; a counter electrode over the electrophoretic display element; a partition layer being in contact with the interlayer insulating film and the counter electrode; and a second flexible substrate over the counter electrode, wherein the electrophoretic display element is surrounded by the partition layer which is provided so as to cover an end portion of the pixel electrode, wherein an upper surface of the amorphous semiconductor film has a depression portion, wherein a first end portion of the gate electrode extends beyond a first end portion of the microcrystalline semiconductor film, and wherein a second end portion of the microcrystalline semiconductor film extends beyond a second end portion of the gate electrode.
