An abrasive wire provides an efficient cutting operation with high accuracy and a longer service life. Abrasive grains are provided around a core wire. The abrasive grains are bonded to the core wire by a light curing resin or an electron beam curing resin which can be cured within a few seconds. Accordingly, the curing operation can be performed while the core wire is moved in the direction of the longitudinal axis of the core wire. Thus, a long abrasive wire can be fabricated at reduced time and cost.

A liquid crystal display panel is composed of a plurality of panel elements. The panel elements are arranged in matrix form in a plane. Each element comprises an upper flexible substrate having a plurality of electric terminals formed thereon and a lower flexible substrate having a plurality of electric terminals formed thereon. Two adjacent panel elements are arranged in such a manner that the terminals of the upper substrate are electrically connected to the terminals of the lower substrate through a conductive resin layer disposed therebetween.
