Abstract
It is an object of the present invention to provide a spacer which has an adequate Young's modulus for a spacer used in an image display panel and allows free adjustment of an electric resistance value, and an image display panel using the spacer. The spacer SPC holds a gap between a back panel PNLincluding a signal line CL, a scanning line GL, and an electronic source ELS provided for the main surface of a back substrate SUB, and a front panel PNLincluding a fluorescent material PH, a black matrix BM, and an anode AD provided for the main surface of a front substrate SUB. The spacer comprises phosphate glass including the same transition metal element with different valences. For electrical conduction, the included same transition metal element with different valences allows the use of hopping conduction between transition metal atoms with different valences to perform adjustment of electric resistance relatively easily. The transition metal element is at least one of vanadium (V), tungsten (W), molybdenum (Mo), niobium (Nb), and iron (Fe).
