Claim of US Patent No. 10,558,082

1. A display apparatus, comprising:a backlight unit configured to emit blue light;
a first base substrate disposed on the backlight 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 blue light blocking pattern disposed on the first inorganic insulation layer on which the data pattern is disposed;
a second inorganic insulation layer disposed on the data pattern and the first inorganic insulation layer;
a shielding electrode disposed on the blue light blocking pattern and overlapping the gate pattern or the data pattern;
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;
a liquid crystal layer disposed between the pixel electrode and the color conversion pattern; and
a thin film transistor disposed on the first base substrate,
wherein the blue light blocking pattern is disposed between the shielding electrode and the first base substrate, and
wherein the blue light blocking pattern overlaps the thin film transistor, and the blue light blocking pattern is disposed between the thin film transistor and the liquid crystal layer.
