Title:
ORGANIC LIGHT EMITTING DISPLAY AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/024658
Kind Code:
A1
Abstract:
Disclosed are an organic light emitting display (200) and a manufacturing method thereof. The manufacture method comprises: forming a gate (20) of a first thin film transistor (T1) on a substrate (10); continuously forming, on the substrate (10), a first insulated composite layer (12) covering the gate (20) of the first thin film transistor (T1), a source (22a) and a drain (22b) of the first thin film transistor (T1) located on the first insulated composite layer (12), a source (32a) and a drain (32b) of a second thin film transistor (T2), and a first storage electrode (40) of a storage capacitor (Cst); forming, on the first insulated composite layer (12), a third insulated layer (16) covering the source (22a) and the drain (22b) of the first thin film transistor (T1), the source (32a) and the drain (32b) of the second thin film transistor (T2) and the first storage electrode (40); forming, on the third insulated layer (16), a gate (30) of the second thin film transistor (T2) and a second storage electrode (42) of the storage capacitor (Cst); forming, on the third insulated layer (16), a second insulated composite layer (18) covering the gate (30) of the second thin film transistor (T2) and the second storage electrode (42); and forming through holes (18') in the second insulated composite layer (18) so that the source (22a) and the drain (22b) of the first thin film transistor (T1) and the source (32a) and the drain (32b) of the second thin film transistor (T2) are exposed.
