Abstract: A manufacturing method of an OLED anode and display device are provided, which the former method comprises the steps: forming an anode-film layer, a material is an ITO, on a substrate; forming a photoresist-film layer on the anode-film layer; patterning the photoresist-film layer to acquire a photoresist-mask pattern, which comprises: an area of photoresist full-retention, photoresist half-retention, and a photoresist full-removal, wherein the photoresist area of half-retention is located between the full-retention and the full-removal; etching the anode film layer to acquire an anode pattern; removing the photoresist half-retention area; perform a plasma treatment to a portion of the anode pattern outside the photoresist full-retention area by adopting a first gas, comprising at least one of O2, N2O, CF4, Ar; removing the photoresist-mask pattern. The disclosure increases the small thickness portion of brightness to compensate for the display unevenness caused by the thickness difference and improve the display quality.

Abstract: The disclosure provides an OLED display device and a process for manufacturing the same, wherein the OLED display device includes a substrate, a first electrode, an organic functional layer, a second electrode, a polymer dispersed liquid crystal (PDLC) layer, and an upper electrode stacked in sequence, wherein the first electrode is an opaque electrode, and the second electrode is a semi-transparent electrode, and a micro-cavity structure consists of the first electrode, the organic functional layer, and the second electrode. The disclosure implements anti-peeping function and ensures the privacy of the display contents of the OLED display device while doing no harm to the organic functional layer. The disclosure also ensures that the display contents of the OLED display device can be dearly seen in a variety of angle.
