Thin film transistor and display apparatus comprising the same

A thin film transistor comprising:

• an auxiliary electrode;
• a gate electrode;
• and
• an active layer including oxide semiconductor material and disposed between the auxiliary electrode and the gate electrode,
• wherein the active layer includes:
• a channel portion including the oxide semiconductor material and overlapped with the gate electrode;
• a first connection portion including conductorized oxide semiconductor material and disposed at a first side of the channel portion;
• and
• a second connection portion including the conductorized oxide semiconductor material and disposed at a second side of the channel portion,
• wherein the channel portion includes a first portion overlapped with the auxiliary electrode and a second portion not overlapped with the auxiliary electrode, and
• wherein the auxiliary electrode overlaps the first portion of the channel portion, a boundary portion between the channel portion including the oxide semiconductor material and the first connection portion including the conductorized oxide semiconductor material, and the first connection portion.
