Claim 11:
12. A display device, comprising:
a substrate;
a first active pattern on the substrate;
a first high permittivity insulation layer on the first active pattern;
a first inorganic insulation layer on the first high permittivity insulation layer;
a second gate insulation layer on the first inorganic insulation layer;
a capacitor electrode on the second gate insulation layer, the capacitor electrode overlapping the first active pattern;
an insulation interlayer on the capacitor electrode; and
a source electrode and a drain electrode on the insulation interlayer and connected to the first active pattern,
wherein a permittivity of the first high permittivity insulation layer is greater than a permittivity of the first inorganic insulation layer, and
wherein the permittivity of the first high permittivity insulation layer is greater than a permittivity of the insulation interlayer.
