Abstract: An electron source (10) has an electron source element (10a) including a lower electrode (12), a drift layer (6) and a surface electrode (7). The drift layer (6) is interposed between the lower electrode (12) and the surface electrode (7). When a certain voltage is applied between the surface electrode (7) and the lower electrode (12) such that the surface electrode (7) has a higher potential than that of the lower electrode (12), a resultingly induced electric field allows electrons to pass through the drift layer (6) and then the electrons are emitted through the surface electrode (7). When a forward-bias voltage is applied between the surface electrode (7) and the lower electrode (12), a reverse-bias voltage is applied after the forward-bias voltage has been applied to release out of the drift layer (6) an electron captured by a trap (9) in the drift layer (6).

Abstract: In a field emission cold cathode device having a block defined by a contour and a plurality of holes arranged in the block, each hole is uniform in shape to obtain a uniform electric current in the block when emitter cones are located in the uniform holes. A distorted hole is not arranged in the block or holes which are susceptible to be distorted are shifted or moved to other zones which are not distorted. Such uniform holes can be also obtained by preparing mask patterns of different sizes and by transcribing the mask patterns onto photoresist.
