Abstract
A an organic light-emitting display apparatus, including a first substrate, a display unit having a plurality of organic light-emitting devices that is formed on the first substrate, a second substrate disposed on the display unit, and a filler included between the first substrate and the second substrate. The organic light-emitting device includes a first electrode formed on the first substrate, an intermediate layer that is disposed on the first electrode and includes an organic emission layer, and a porous second electrode disposed on the intermediate layer.
Claims21
An organic light-emitting display apparatus comprising:
- a first substrate;
- a display unit disposed on the first substrate and comprising organic light-emitting devices;
- a second substrate facing the display unit;
- and
- a color filter disposed on the second substrate,
- wherein the organic light-emitting devices each comprise a first electrode disposed on the first substrate, an intermediate layer disposed on the first electrode and comprising an organic emission layer, and a porous second electrode disposed on the intermediate layer, and
- wherein pores of the porous second electrode prevent a localized concentration of impurities in the porous second electrode.
A method of manufacturing an organic light-emitting display apparatus, the method comprising:
- forming a display unit on a first substrate;
- disposing a filler on the display unit;
- and
- disposing a second substrate on the filler,
- wherein:
- the forming of the display unit on the first substrate comprises:
- forming a first electrode on the first substrate;
- forming an organic emission layer on the first electrode;
- and
- forming a porous second electrode on the organic emission layer;
- the method further comprises:
- forming a porous separation layer comprising an organic material between the porous second electrode and the filler;
- and
- forming a sealant between the first substrate and the second substrate bonding the first substrate and the second substrate, the sealant surrounding the display unit and the filler and having a predetermined spacing from the display unit;
- the filler covers the porous second electrode, a side of the porous separation layer, and a top of the porous separation layer;
- the filler is formed so as not to extend beyond the sealant;
- and
- the filler comprises an organic material and directly contacts the porous separation layer.
