Abstract:
1. A thin film transistor device comprising: a first thin film transistor element and a second thin film transistor element that are arranged so as to be adjacent to each other with a gap therebetween, wherein each of the first thin film transistor element and the second thin film transistor element comprises: the thin film transistor device further comprises partition walls disposed on the insulating layer and partitioning the semiconductor layer of the first thin film transistor element from the semiconductor layer of the second thin film transistor element, the partition walls having liquid-repellant surfaces and defining a first aperture and a second aperture, the first aperture surrounds at least a part of each of the source electrode and the drain electrode of the first thin film transistor element, the second aperture is adjacent to the first aperture and surrounds at least a part of each of the source electrode and the drain electrode of the second thin film transistor element, a bottom portion of each of the first and second apertures includes a source electrode portion being a bottom portion of the source electrode and a drain electrode portion being a bottom portion of the drain electrode, in plan view of the bottom portion of the first aperture, a center of a total of areas of the source electrode portion and the drain electrode portion is offset from a center of area of the bottom portion in a direction opposite a direction of the second aperture, and in plan view of the bottom portion of the second aperture, a center of a total of areas of the source electrode portion and the drain electrode portion is offset from a center of area of the bottom portion in a direction opposite a direction of the first aperture.
