Abstract:
1. An organic light emitting diode display device, comprising: a substrate having an emission section and a non-emission section; a semiconductor layer located on the substrate; a gate dielectric layer located over an entire front surface of the substrate; a gate electrode located in correspondence to the semiconductor layer; a dielectric layer located over the entire front surface of the substrate; source and drain electrodes and a first electrode located on the dielectric layer and electrically connected to the semiconductor layer, the first electrode being located on the emission section of the substrate; a pixel definition layer comprised of a silicon-containing inorganic layer having no greater than 18 wt % of silicon, the pixel definition layer defining an opening that exposes a part of the first electrode, the inorganic layer of the pixel definition layer overlaying a region that includes the source electrode and drain electrode; a spacer comprised of an organic layer, the spacer being located on the pixel definition layer and located on the non-emission section of the substrate; an organic film layer located within the opening and upon the first electrode; and a second electrode located over the entire front surface of the substrate, wherein the spacer does not overlap the organic film layer.
