OLED display panel
View Patent ↗An OLED display panel and manufacturing method of the panel are provided in which a terminal electrode is exposed by performing etching with fixed etching conditions without performing step processing. A terminal region comprised from a plurality of metal electrodes 2 conducting with an organic light emitting element of a display part is formed above a substrate 1 . Next, a stacked sealing film comprised from a first SI contained inorganic layer, an organic resin layer and a second Si contained inorganic layer is formed above a surface of the display part and the terminal region 6 . Next, etching is performed using etching conditions suitable for the first and the second SI contained inorganic layer while the display part is masked, the first and the second SI contained inorganic layer above the metal electrode 2 are removed and a surface of the metal electrode 2 is exposed.
1. An OLED display panel comprising:
a substrate;
a display part including a plurality of organic light emitting elements formed above the substrate;
a plurality of electrodes formed in a band shape above the substrate and each capable of conducting with an electrode above another substrate respectively; and
a stacked sealing film formed above the display part and including a first Si contained inorganic layer, an organic resin layer and a second Si contained inorganic layer in sequence from the substrate side;
wherein the first Si contained inorganic layer and the organic resin layer are formed between the plurality of electrodes.
2. The OLED display panel according to claim 1 , wherein a SIO layer is formed between the first Si contained inorganic layer and the organic resin layer.
3. The OLED display panel according to claim 1 , wherein an amorphous silicon layer is formed between the first Si contained inorganic layer and the organic resin layer.
4. The OLED display panel according to claim 1 , wherein in the display part, a layer with same material as a bank sectioning each organic light emitting element is formed between the plurality of electrodes, and the first Si contained inorganic layer and the organic resin layer the same as the stacked sealing film are formed between the layer having the same material as the bank and each electrode.
5. The OLED display panel according to claim 4 , wherein wiring conducting with an organic light emitting element forming the display part is formed above the substrate, and an ITO thin film is formed across a surface of the electrode and a surface of the wiring.
6. The OLED display panel according to claim 5 , wherein the ITO thin film extends up to a surface of the layer having the same material as the bank sectioning each organic light emitting element.
