Abstract: An organic light emitting diode display device includes a substrate, a driving transistor, a switching transistor, a first light absorbing layer, an organic insulating layer, and a sub-pixel structure. The substrate includes a first region and a second region. The driving transistor is disposed in the first region on the substrate. The switching transistor is disposed in the second region on the substrate, and includes a metal-oxide-based semiconductor. The first light absorbing layer is disposed on the driving and switching transistors. The organic insulating layer is disposed directly on the first light absorbing layer. The sub-pixel structure is disposed on the organic insulating layer.

Abstract: An inkjet printing apparatus includes: a stage, which reciprocates in forward and reverse directions opposite to each other and has a target substrate disposed thereon; an inspection device including a film disposed outside the stage and a measurement unit which measures an inspection pattern provided on the film; and a head assembly, which moves along one direction crossing the forward direction and has a plurality of heads which supplies a liquid composition to the target substrate. The head assembly moves in the one direction to overlap the film and sprays the composition onto the film to form an inspection pattern.

Abstract: A display apparatus is disclosed that includes a substrate, a display element layer a color filter layer, an input-sensing layer, and a reflection-adjusting layer disposed between the display element layer and the color filter layer, or between the color filter layer and the input-sensing layer. The color filter layer includes a first color filter and a second color filter. The first color filter is arranged in a first emission area and the second color filter is arranged in a second emission area. The reflection-adjusting layer is integrally formed over the first emission area, the second emission area, and a third emission area.
