ABSTRACT:
To realize a field emission type image display device which can obtain a high current density at low voltage driving, assuming a diagonal screen size of the display region as D(mm), the number of the pixels which are arranged in the x direction as Nh, the number of the pixels which are arranged in the y direction as Nv, the distance between the electron passing apertures formed in the strip-like electrode elements which constitute the control electrodes as db(mm), the distance between the electron source and the strip-like electrode element as Lkg(mm), and an aperture diameter of the electron passing apertures as φG(mm),provided that the aperture diameter φG(mm) is expressed by the following formula (45),D3·Nh2+Nv2-2⁢db>(-0.23·ln⁡(db)+0.49)·Lkg+0.02·ln⁡(db)+0.125(45)the following formula (46) is established.in-line-formulae description="In-line Formulae" end="lead"?(0.46·ln(db)+2.5)·Lkg+0.006·ln(db)+0.04≦φG≦(−0.41·ln(db)−0.68)·Lkg+0.014·ln(db)+0.145  (46)in-line-formulae description="In-line Formulae" end="tail"?
