Abstract: A transistor panel may include a substrate, a transistor, a first inorganic buffer layer, and an inorganic fluorine-containing buffer layer. The transistor may overlap the substrate and may include a semiconductor layer. The first inorganic buffer layer may be disposed between the substrate and the semiconductor layer. The inorganic fluorine-containing buffer layer may be disposed between the first inorganic buffer layer and the semiconductor layer and may contain fluorine in a range of 0.5 at % to 2 at %.

Abstract: A light emitting device includes: a substrate; a first electrode and a second electrode on the substrate and spaced apart from each other; a light emitting diode between the first electrode and the second electrode and connected to the first and second electrodes; a first contact on the first electrode; and a second contact on the second electrode. The first contact contacts the first electrode and a first portion of the light emitting diode, and the second contact contacts the second electrode and a second portion of the light emitting diode.
