US Patent 9978727 Display apparatus and manufacturing method thereof

A display apparatus including a light emitting diode part including a plurality of regularly arranged light emitting diodes, and a thin-film transistor (TFT) panel part including a plurality of TFTs configured to drive the light emitting diodes disposed on the TFT panel part. The light emitting diode part further includes a transparent substrate disposed on the light emitting diodes, and a phosphor layer disposed on the transparent substrate and configured to emit at least one of blue light, green light, and red light by converting at least a portion of a wavelength of light emitted from the light emitting diodes, in which a thickness of the transparent substrate is less than a thickness of the phosphor layer.
