1. A display device comprising:
a thin-film transistor layer comprising a display metal layer and a display protection layer protecting the display metal layer in a layer above the display metal layer, the thin-film transistor layer formed at a display region;
a terminal metal layer formed at a frame region surrounding the display region using a same material as the display metal layer; and
a terminal protection layer formed using a same material as the display protection layer,
wherein the display metal layer and the display protection layer are formed to match each other,
the terminal metal layer and the terminal protection layer are formed to match each other,
the display protection layer covers an upper face and both side faces of the display metal layer, and
the terminal protection layer covers an upper face and both side faces of the terminal metal layer,
the display metal layer and the display protection layer are formed at the display region,
the terminal metal layer and the terminal protection layer are formed at the frame region, and
a tip end face of the terminal metal layer is covered with the metal protection layer.
