摘要： A process for manufacturing a thin-film electron source including a lower electrode (11), an upper electrode, and an insulating layer sandwiched between the lower electrode (11) and the upper electrode. The process comprises a first step of forming an anodized film over the surface of the lower electrode (11) by an anodizing method, a second step of etching the surface side of the anodized film, and a third step of forming an anodized film again over the surface of the lower electrode (11) by an anodizing method to form said insulating layer. As a result, the film thickness of such an outer layer (26) of the insulating layer containing much impurity can be reduced to reduce the number of electron trapped.

摘要： As the top electrode material of a thin-film electron emitter, a material having a bandgap wider than that of Si and electrical conductivity is used. In particular, a conductive oxide such as an SnO2 or ITO film and a wide-bandgap semiconductor such as GaN or SiC are employed. The electron energy loss in a top electrode through which hot electrons pass can be reduced so as to enhance the electron emission efficiency. A high emission current can be obtained in the case of the same diode current as a prior art. In addition, in the case of the same emission current density as a prior art, a small driving current is enough. A bus line and driving circuits can be simplified.

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.

A film of an upper electrode of a thin film type electron source for each pixel constituted by an insulating layer serving as an electron accelerating layer on the lower electrode and the upper electrode is formed on two stripe electrodes of the upper bus electrode in that pixel and another upper bus electrode in an adjacent pixel by sputtering. Then, the upper electrode is separated by self-alignment due to a setback portion of the metal film lower layer and an appentice of the metal film upper layer of the corresponding upper bus electrode. Thus, a thin film type electron source separated in accordance with each pixel is formed.

摘要： Disclosed is a display device with improved brightness achieved by increasing electron emission efficiency of a thin film cathode. Phosphors are irradiated with electrons emitted to a vacuum through a flat thin film which is thinner than 5 nm and is disposed so as to face the phosphors. A top electrode for emitting the electrons is formed by stacking thin films of Ir, Pt, and Au, and performing a heat treatment so as to reconstruct the top electrode to have a structure in which thick island parts and a flat thin film part mixedly exist.
