Fiber containing carbon, substrate and electron emission device using fiber containing carbon, electron source using the electron emission device, display panel using the electron source, and information displaying/playing apparatus using the display panel, and a method of manufaturing thereof

摘要

The invention provides a fiber containing carbon which is less deteriorated in terms of electron emission characteristic, is excellent in terms of reproducibility, and can in addition be formed at a low cost, a substrate and electron emission device using the fiber containing carbon, an electron source using the electron emission device, a display panel using the electron source, and an information displaying/playing apparatus using the display panel, and a method of manufacturing these. The manufacturing method comprises a first step of preparing a substrate (substrate 1) equipped with a catalyst (catalyst layer 3) on its surface; and a second step of causing the fiber containing carbon (carbon fiber 4) to grow using the catalyst, whereby the second step comprises, in order to decrease, from a midway point of time in this step, the growth rate at which the fiber containing carbon grows, a sub-step of controlling the growth conditions for the fiber containing carbon. <IMAGE>
