Abstract
Disclosed is a plasma display apparatus comprising: discharge spaces of red which emit lights of red; discharge spaces of green which emit lights of green; discharge spaces of blue which emit lights of blue; and photo masks which are formed and arranged in order that an aperture of each of the discharge spaces of red may be wider than an aperture of each of the discharge spaces of green in area and an aperture of each of the discharge spaces of blue may be wider than the aperture of each of the discharge spaces of red in area.
Claims19
A plasma display apparatus comprising:
- discharge spaces of red which emit red light;
- discharge spaces of green which emit green light;
- discharge spaces of blue which emit blue light;
- and
- photo masks which are formed and arranged in order that an aperture of each of said discharge spaces of red is wider than an aperture of each of said discharge spaces of green in area and an aperture of each of said discharge spaces of blue is wider than the aperture of each of said discharge spaces of red in area, wherein said photo masks include vertical photo masks, and wherein brightness of said lights varies according to sizes of said apertures, wherein a width of each of vertical photo masks varies in dependence on whether a corresponding discharge space is said discharge spaces of red, said discharge space of green, or said discharge space of blue.
