Display apparatus comprising a color conversion pattern and a light blocking pattern disposed on a data pattern of a thin film transistor

A display apparatus, comprising:

• a light unit configured to emit blue light;
• a first base substrate disposed on the light unit;
• a gate pattern disposed on the first base substrate, the gate pattern comprising a gate electrode;
• a first inorganic insulation layer disposed on the gate pattern;
• a data pattern disposed on the first inorganic insulation layer, the data pattern comprising a drain electrode;
• a light blocking pattern disposed on the first inorganic insulation layer;
• a second inorganic insulation layer disposed on the data pattern and the first inorganic insulation layer;
• a pixel electrode disposed on the second inorganic insulation layer, and electrically connected to the drain electrode;
• a color conversion pattern overlapping the pixel electrode, the color conversion pattern comprising a quantum dot or phosphor;
• and
• a thin film transistor disposed on the first base substrate,
• wherein the light blocking pattern overlaps the thin film transistor, and the light blocking pattern is disposed on the first base substrate.
