摘要：
A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, and a plurality of electron emitters disposed on a principal surface of the fixed substrate. A light reflecting film is disposed on a portion of the principal surface of the fixed substrate which is free of the electron emitters. An anode electrode in the form of a transparent electrode is disposed on a substantially entire reverse side of the transparent substrate. Phosphor layers are disposed on the anode electrode at respective positions facing the electron emitters.
