Abstract
A display device includes a substrate, an active pattern disposed on the substrate, a gate electrode overlapping the active pattern, an inorganic insulation layer covering the active pattern, a source metal pattern and an etch-delaying pattern. The source metal pattern includes a first portion that is disposed on the inorganic insulation layer, and a second portion that passes through the inorganic insulation layer and electrically contacts the active pattern. The etch-delaying pattern is disposed between the active pattern and the first portion of the source metal pattern, contacts the second portion of the source metal pattern, and includes a different material from the inorganic insulation layer.
