Display device and production method thereof

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).

A wiring glass substrate includes a glass substrate formed of glass and having a plurality of holes formed at predetermined positions, bumps so formed as to be connected to a conductive material filling the holes and wirings formed on a surface opposite to a surface having the bumps formed thereon and electrically connecting a plurality of connection terminals arranged in intervals different from intervals of the holes to the conductive material. The shape of the conductive material is porous and porous electrodes are bonded to the inner wall surfaces of the holes by an anchor effect to increase the strength of the glass substrate.
