Abstract

The present disclosure relates to a via-hole connection structure and a method of manufacturing the same and an array substrate and a method of manufacturing the same. In an embodiment, a method of manufacturing a via-hole connection structure, includes the following steps of: forming a first conductive layer on a substrate, and patterning the first conductive layer to form a first conductive pattern on which a first photoresist pattern is provided; forming a first insulation layer covering the first conductive layer and the first photoresist pattern; patterning the first insulation layer to form a first via-hole from which at least a portion of the first photoresist pattern is exposed; removing the at least a portion of the first photoresist pattern exposed from the first via-hole; and forming a second conductive pattern, wherein the second conductive pattern is electrically connected to the first conductive pattern through the first via-hole.
