Touch display panel and method of manufacturing the same

A method of manufacturing a touch display panel, comprising:

• providing a thin-film transistor substrate;
• forming a pixel defining layer comprising a first opening on the thin-film transistor substrate;
• forming a light emitting structure in the first opening;
• forming a thin film encapsulation layer covering the light emitting structure and the pixel defining layer;
• forming a first metal layer and a first insulation layer on the thin film encapsulation layer;
• forming a first photoresist pattern comprising a first portion having a first height and a second portion having a second height less than the first height on the first insulation layer;
• forming a first metal pattern and a first insulation pattern by patterning the first metal layer and the first insulation layer using the first photoresist pattern;
• and
• forming a second metal pattern on the thin film encapsulation layer on which the first insulation pattern is formed.
