Abstract
The present disclosure provides a display panel and a manufacturing process of the display panel. The manufacturing process of the display panel includes: successively depositing a plurality of thin-film layers on an auxiliary electrode layer, the compactness of a single thin-film layer among the plurality of thin-film layers gradually increasing from bottom to top; forming a preset pattern by the plurality of thin-film layers having a same width; dry-etching the plurality of thin-film layers so that the width of a single thin-film layer among the plurality of thin-film layers gradually increases from bottom to top, to form a plurality of cathode separators having an inverted trapezoid shape. The manufacturing process of the cathode separator is highly stable.
