Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A display apparatus, comprising:
a base substrate;
a first active pattern disposed on the base substrate, the first active pattern including polycrystalline silicon;
a gate electrode overlapping a first portion of the first active pattern;
at least one first insulation layer disposed on the gate electrode;
a source electrode electrically connected to a second portion of the first active pattern and a drain electrode electrically connected to a third portion of the first active pattern;
a second active pattern disposed on the first insulation layer, the second active pattern including an oxide semiconductor; and
an oxide semiconductor pattern disposed between the source electrode and the drain electrode on the first insulation layer, the oxide semiconductor pattern being adjacent to and separate from the source electrode and the drain electrode such that the oxide semiconductor pattern is not electrically connected to the source electrode and the drain electrode.
