Abstract:
1. A thin film transistor element comprising: a gate electrode; an insulating layer disposed on the gate electrode; a source electrode and a drain electrode disposed on the insulating layer with a gap therebetween; an organic semiconductor layer disposed on the source electrode and the drain electrode to cover the source electrode and the drain electrode and to fill the gap between the source electrode and the drain electrode, and in contact with the source electrode and the drain electrode; a liquid-philic layer disposed on the insulating layer and having higher liquid philicity than the insulating layer, the liquid-philic layer being separated from the source electrode and the drain electrode, and partition walls disposed on the insulating layer and having liquid-repellant surfaces, the partition walls defining at least a first aperture and a second aperture, wherein the first aperture surrounds at least a part of each of the source electrode, the drain electrode, and the liquid-philic layer, a bottom portion of the first aperture includes a source electrode portion that is a bottom portion of the source electrode, a drain electrode portion that is a bottom portion of the drain electrode, and a liquid-philic layer portion that is a bottom portion of the liquid-philic layer, the second aperture is spaced from the first aperture with a gap therebetween and the organic semiconductor layer is not disposed within an area of the second aperture, and in a plan view of the bottom portion of the first aperture, a center of an area of the liquid-philic layer portion is offset from a center of an area of the bottom portion of the first aperture in a first direction opposite a direction in which the second aperture is spaced from the first aperture.
