Abstract: A display apparatus including a light-emitting device and a method of forming the same are provided. The light-emitting device may be electrically connected to the driving circuit. A first planarization layer may be disposed on the driving circuit, a second planarization layer may be disposed on the first planarization layer, and the light-emitting device may be disposed on the second planarization layer. An upper surface of the second planarization layer toward the light-emitting device may be parallel with a surface of a device substrate supporting the light-emitting device and the driving circuit. Thus, in the display apparatus and the method of forming the same, decreasing the quality of an image due to differences in the generation position of the light emitted from the light-emitting device may be prevented.

Abstract: A display device including a backlight unit that includes a barrier layer disposed between a light-emitting chip and an electrode pad to reduce the contact area between a solder and the electrode pad due to the barrier layer, so that a portion of the electrode pad overlapping with the barrier layer is left behind without being diffused into the solder, and rework can be performed on a process of mounting the light-emitting chip.

Abstract: Provided are a roller apparatus, a printing method and a method of fabricating an LCD device using the same, which can minimize the number of processes and a printing defect. In the printing method, first patterns are formed on a blanket. The first patterns have different surface energy from that of the blanket, and the blanket is formed around a roller. The roller is rotated and a printing material is dropped to form second patterns on the blanket between the first patterns. The second patterns are transferred from the roller onto a substrate.
