Abstract: Provided is a photosensitive resin composition including a reactive unsaturated compound, an alkali soluble resin, an initiator, and a pigment. The reactive unsaturated compound is selected to cause the composition to exhibit high-resolution pattern properties that facilitate forming a pixel defining film in a display device. The reactive unsaturated compound may be an acryl-based compound having at least three ethylenically unsaturated double bond groups in molecules and having a viscosity of about 200 mPa s to about 280 mPa s at 40° C. A display device including such pixel defining film is also presented.

Abstract: A display device is disclosed that includes a substrate, a conductive layer, and a pixel defining layer. The substrate includes a first display area including pixels, a second display area including the pixels, and a transmissive area formed between the pixels of the second display area. The conductive layer is disposed in the second display area outside of the transmissive area. The pixel defining layer overlaps the conductive layer and is disposed such that an end of the pixel defining layer adjacent to the transmissive area is substantially aligned with an end of the conductive layer adjacent to the transmissive area.

Abstract: A display panel is disclosed that includes a base layer including a first pixel area and a second pixel area adjacent to the first pixel area, a pixel definition layer disposed on the base layer and provided with a pixel opening defined therethrough to correspond to each of the first pixel area and the second pixel area, and a first electrode of which at least a portion is disposed in the pixel opening. The pixel definition layer includes a first slant portion, a second slant portion spaced apart from the first slant portion, a first convex portion disposed between the first slant portion and the second slant portion and adjacent to the first slant portion, and a first flat portion disposed between the first slant portion and the second slant portion and adjacent to the second slant portion.
