Abstract: A front emission type display device is provided. In the display device, light generated by a light-emitting element which is disposed on a first substrate can be emitted to the outside through a color filter and a second substrate, so that an image can be realized on an outer surface of the second substrate. In the display device, a space between a first device passivation layer on the light-emitting element, and a second device passivation layer on the second substrate can be filled by the color filter and a pixel defining pattern disposed on a side surface of the color filter. Thus, in the display device, the distortion of the first substrate and the second substrate can be prevented or reduced.

Abstract: A display apparatus can include a substrate having a plurality of sub-pixels and a contact unit. The display apparatus further includes at least one transistor disposed in each sub-pixel, a light emitting device disposed in each sub-pixel and having a first electrode, an organic layer, and a second electrode, an auxiliary electrode disposed in the contact unit to supply a voltage to the light emitting device, and a blocking layer disposed on the auxiliary electrode to block moisture from outside. The blocking layer includes a first pattern made of an orthogonal material and a second pattern on the first pattern. A width of the blocking layer is smaller than a width of the auxiliary electrode so that the auxiliary electrode is extended to outside of at least one side of the blocking layer and the auxiliary electrode is exposed to the outside.
