An OLED(Organic Light Emitting Display) apparatus is provided to improve the adhesive strength between a pixel substrate and an encapsulation substrate by constantly maintaining a space between the pixel substrate and an encapsulation substrate. An OLED apparatus includes a pixel substrate(100), an encapsulation substrate(200), and a sealing unit(300). A pixel is arranged on the pixel substrate(100). The encapsulation substrate(200) is arranged to be opposite to the pixel substrate(100). The sealing unit(300) connects the pixel substrate(100) and the encapsulation substrate(200) by being arranged according to the circumference of an edge of the pixel substrate(100). The OLED apparatus has a rough surface by processing one connected surface among the substrates with a sand blast on a connected part between the substrates where the sealing unit(300) is positioned. |
