Visible transparency is one of the attributes pursued in the advancement of display devices. Such a transparency can be realized in a plasma display device simply by applying Y(V,P)O 4 :Eu red‐, Y(V,P)O 4 :Tm blue‐, and LaPO 4 :Ce,Tb green‐emitting nanophosphors with a controlled particle size and reasonable luminescence. The nanophosphors of three primary colors are all hydrothermally synthesized and annealed at appropriate conditions. Highly transparent, uniform emissive layers are deposited by screen‐printing the nanophosphor pastes. Using respective screen‐printed nanophosphor layers of red, blue, and green, monochromatic transparent test panels of plasma display are fabricated and characterized. Ultimately, a white‐luminescing full‐color transparent panel is successfully demonstrated by line‐patterning the individual nanophosphor layers. Furthermore, for an effort to extract more photons and thus improve the brightness of the test panel, polystyrene monolayer‐based 2D photonic crystal is introduced as a scattering medium on the outer surface of the panel and its usefulness was proved.
