ELECTRODE PART, LIGHT SOURCE, ILLUMINATING DEVICE, AND LIQUID CRYSTAL DISPLAY

摘要

An electrode part (1), is installed in a light source in which an electron-emissive material (7) is heated to emit thermions for causing arc discharge for light emission. The electrode part is equipped with a filament (5) for heating the electron-emissive material (7) and a plate electrode (2) for performing arc discharge, separetely. By such a constitution, an electrode part for suppressing the breakage of an electrode, a light source, an illuminating device, and a liquid crystal display can be provided.
