摘要： PROBLEM TO BE SOLVED: To reduce the effect by a member to emission electrons in a case where the member such as a spacer is provided, by coating the front surface of a base material of the spacer with a high resistance film as a first layer and coating the first layer with a second layer having a secondary electron emission coefficient lower than that of the first layer except a partial region. SOLUTION: Spacers 1020 are provided for preventing an airtight container from being broken caused by atmospheric pressure or unexpected impact, and each spacer 1020 is provided with a high resistance film as a first layer for preventing charge on the front surface of an insulating member. A second layer 1021 having a lower secondary electron emission coefficient is formed on a specified region of the high resistance film. The first layer neutralizes and removes electric charge charged on the front surface of the spacer 1020 to prevent the spacer 1020 from being largely charged. The second layer 1020 is made of a material having lower secondary electron emission coefficient to prevent the front surface of the spacer from being positive-charged due to electron incidence to the front surface of the spacer, such as re-incidence of directly incident electrons, reflected electrons or secondary electrons.

摘要： PROBLEM TO BE SOLVED: To restrict the deviation of electron orbit from a desirable orbit by having a film including at least carbon nitride in a surface of a first member as a spacer for maintaining a space between a first board and a second board. SOLUTION: A spacer 22 as a first member is formed with a carbon nitride film 23 in a surface of an insulating base material 24, and provided so as to receive the atmospheric pressure at the time of forming inside of a case into vacuum so as to avoid the breakdown or deformation of the case. Material, shape, arrangement, the number of arrangement of the spacer 22 are decided in consideration of shape and a coefficient of thermal expansion of the case, atmospheric pressure and heat to be applied to the case, and as a shape, flat shape, crossing shape, L-shape and cylindrical shape are available. The insulating base material 24 is made of the material having a coefficient of thermal expansion nearly equal to that of a rear place formed with an electron emitting element and a face plate formed with the phosphor, or a material having high elasticity and capable of easily absorbing the thermal deformation is sued. With this structure, influence by the charge can be reduced so as to improve the reproducibility.

摘要： PURPOSE: To suppress the charging of cations to an intermediate member to emit electrons by an intended starting. CONSTITUTION: The electron emitted from an electron source 5 is collided with a metal back 8 to make a fluorescent film luminescent for display, and a particle having a positive charge is emitted at that time. The particle falls, drawing a parabola, but when it collides with a spacer 11 at that time, it is charged there to have an influence on the starting of the electron emitted from the electron source 5. Thus, in order to avoid the collision of the particle emitted from the metal back 8 with the spacer 11, the form of the spacer 11 is set in such a manner that the lower bottom is smaller than the upper bottom.
