Abstract:
A flat type display apparatus using a plasma discharge, comprising:a first substrate capable of passing visible light; a second substrate opposed to said first substrate at a predetermined gap; a discharge gas formed of Xe excluding a halogen sealed in said gap; excitation means for exciting the discharge gas to generate UV rays, the excitation means including a first electrode arranged on a side of said first substrate opposing said second substrate, and a second electrode arranged on a side of said second substrate opposing said first substrate; and photoconversion means, including a phosphor layer formed on the second electrode, for emitting predetermined visible light on the basis of the UV rays, said phosphor layer including a first region emitting a red component of the visible light, a second region emitting a blue component of the visible light, and a third region emitting a green component of the visible light and wherein the thickness of the first, second and third regions are different, wherein the discharge gas is caused by said excitation means to perform excimer light emission for generating UV rays.
