Thermal head and display device.

摘要

In a planar thermal head and a thermal display incorporating it, a plurality of parallel first electrode lines 24 are formed on one side of an electrically resistive layer 25, and a plurality of parallel second electrode lines 26 are formed on the other side of the resistive layer, and oriented to intersect the first parallel electrode lines. A pair of electrodes respectively constituted by part of or by other means connected to one of the first electrode lines 24 and one of the second electrode lines 26 are positioned on opposite sides of the resistive layer 25 for causing a current flow through the resistive layer 25, and a part of the resistive layer 25 through which a current is made to flow by the pair of electrodes 24, 26 forms a thermal dot.
