Display device
According to one embodiment, a display device including an insulating substrate, an organic film on the insulating substrate, and a switching element located between the insulating substrate and the organic film and including a semiconductor layer, a source electrode, and a drain electrode, the organic film including a first removed portion at a position overlapping the semiconductor layer between the source electrode and the drain electrode of the switching element.
1. A display device comprising:
an insulating substrate;
an organic film disposed on the insulating substrate and including a first removed portion;
a switching element located between the insulating substrate and the organic film and comprising a semiconductor layer, a gate electrode, a source electrode, and a drain electrode; and
a metal layer located in a same layer as the source electrode and the drain electrode and overlapping the first removed portion, wherein
the first removed portion overlaps the semiconductor layer between the source electrode and the drain electrode of the switching element, and
the metal layer does not overlap the gate electrode.
2. The display device of claim 1 , wherein
the metal layer is a heat dissipating plate, and
the first removed portion penetrates the organic film toward the heat dissipating plate.
3. The display device of claim 1 , wherein
the metal layer is a heat dissipating plate, and
the organic film is interposed between the first removed portion and the heat dissipating plate.
4. The display device of claim 2 , further comprising:
a reflective film located on the organic film,
wherein
the reflective film is in contact with the heat dissipating plate inside the first removed portion.
5. The display device of claim 2 , wherein
the organic film includes a second removed portion at a position overlapping the heat dissipating plate.

a source line connected to the source electrode,
wherein
the semiconductor layer includes a first part overlapping the source line and a second part overlapping the metal layer, and
a width of the second part is larger than a width of the first part.
7. The display device of claim 6 , wherein
the width of the second part is two or more times as large as the width of the first part.
8. The display device of claim 1 , wherein
the switching element comprises the gate electrode located at an upper position than the semiconductor layer.
9. The display device of claim 1 , wherein
the switching element comprises the gate electrode located at a lower position than the semiconductor layer.
