ABSTRACT:
In an FED (Field Emission Display), lowering of a color temperature is suppressed which is caused by that light emission luminance of respective color phosphors is different from each other so as to achieve a better white balance. A display apparatus is equipped with a cathode substrate containing a plurality of electron emitter elements, and an anode substrate. The anode substrate is arranged opposite to the cathode substrate, and contains three colors of red, green, blue phosphors which are excited by electrons emitted from the electron emitter elements so as to emit light. Then, an area of either the red phosphor or an area of the blue phosphor is made smaller than an area of the green phosphor.
