摘要： An MIM electron source is comprised of a lower electrode, an insulation film and an upper electrode. By depositing a coat film on the upper electrode through a sputter process using a sputter target of alkaline glass having a modifier component of an alkaline metal oxide or alkaline earth metal oxide, the work function of the upper electrode can be lowered. As a result, the electron emission efficiency can be increased stably.

摘要： The present invention prevents a phenomenon that some electrons emitted from electron sources are charged to partition walls from influencing trajectories of the electrons thus preventing the shortage of excitation of phosphor layers. An image display device includes electron sources to which an electric current is supplied from scanning signal lines by way of current supply electrodes. The image display device also includes partition walls which are arranged on at least some of the scanning signal lines. Further, the current supply electrodes are connected with the electron sources on a downstream side of the scanning signal lines.

摘要： In a matrix electron emitter display using a thin-film electron emitter, a required resistance value of a top electrode, which value is determined by voltage drop at the top electrode, is small, and selection of a material and film thickness of the top electrode have been limited. Use of cathode structure which improves the capability of feeding from a feeding line to a thin-film electron emitter element improves the electron emission efficiency, and permits achieving higher luminance and lower power of a display apparatus.
