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. A manufacturing method of an OLED display panel comprising:
forming a display part including a plurality of organic light emitting elements above a substrate;
forming a plurality of electrodes in a band shape above the substrate, each capable of conducting with an electrode above another substrate;
forming a recessed part between the electrodes above the substrate;
forming a stacked sealing film including a first contained inorganic layer, an organic resin layer and a second contained inorganic layer in sequence from the substrate side above the display part and a terminal region which have the plurality of electrodes; and
exposing a surface of the plurality of electrodes by performing etching using etching conditions suitable for the first Si contained inorganic layer and the second Si contained inorganic layer while the display part is masked.
