Abstract
A method for fabricating a field emission display (100) includes the steps of providing a cathode plate (102), providing an anode plate (104), providing a spacer substrate (160) made from a bulk spacer material (109), cutting the spacer substrate (160) to define a spacer (108) having a surface (107), passivating the surface (107) of the spacer (108) using the bulk spacer material (109) to form a passivation layer, and disposing the spacer (108) between the cathode plate (102) and the anode plate (104). A field emission display (100) which includes a cathode plate (102) having a plurality of electron emitters (124), an anode plate (104) opposing the cathode plate (102), and a spacer (108) extending between the cathode plate (102) and anode plate (104). The spacer (108) has a passivation layer made from bulk spacer material (109).
