A light emitting display apparatus is disclosed. The light emitting display apparatus includes: a substrate; and a plurality of pixels disposed on a pixel area on the substrate. Each of the plurality of pixels includes: a first circuit layer including a first pixel circuit including a driving transistor; a second circuit layer overlapping the first circuit layer, wherein the second circuit layer includes a second pixel circuit including a data supply transistor configured to supply a data signal to the first pixel circuit; a circuit insulating layer between the first circuit layer and the second circuit layer; and a light emitting diode layer including a light emitting diode electrically connected with the first pixel circuit.

Light emitting display apparatus

A deposition apparatus, such as an ultra-fine pattern deposition apparatus is provided. A deposition apparatus includes a base substrate, a heating assembly, a deposition source material and a pattern guide. The heating assembly has at least a part thereof included in the base substrate. The deposition source material is disposed on the heating assembly. The pattern guide overlies the base substrate and has a portion thereof above the heating assembly and the deposition source material. The pattern guide has an opening including a laterally recessed lower region and an upper region. The opening extends from an upper surface of the base substrate to an upper surface of the pattern guide. The lower region of the opening is wider than the upper region of the opening, and the opening of the pattern guide is configured to guide a material emitted from the deposition source material to a target region on a target substrate that is spaced apart from the base substrate.
