Abstract
A planar thermal head and a thermal display incorporating it comprising a plurality of parallel first electrode lines formed on one side of an electrically resistive layer, and a plurality of parallel second electrode lines formed on the other side of the resistive layer the second electrode lines are oriented to intersect the first parallel electrode lines. A pair of electrodes respectively constituted of part of or connected to one of the first electrode lines and one of the second electrode lines are positioned on opposite sides of the resistive layer for causing a current flow through the resistive layer, and a part of the resistive layer through which a current is made to flow by the pair of electrodes forms a thermal dot.
