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;

    a semiconductor layer disposed on the source electrode and the drain electrode so as to cover the source electrode and the drain electrode and fill the gap between the source electrode and the drain electrode, and being 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 separate from the source electrode and the drain electrode, andpartition walls disposed on the insulating layer and having liquid-repellant surfaces, the partition walls defining at least a first aperture and a second aperture, whereinthe 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 thus including a source electrode portion being a bottom portion of the source electrode, a drain electrode portion being a bottom portion of the drain electrode, and a liquid-philic layer portion being a bottom portion of the liquid-philic layer,the second aperture is located apart from the first aperture with a gap therebetween and the semiconductor layer is not formed within an area surrounded by the second aperture, andin plan view of the bottom portion of the first aperture, a center of area of the liquid-philic layer portion is offset from a center of area of the bottom portion of the first aperture in a first direction opposite a direction of the second aperture.
