DISPLAY PANEL SUBSTRATE, DISPLAY PANEL, DISPLAY APPRATUS, AND METHOD FOR MANUFACTURING DISPLAY PANEL SUBSTRATE
First Claim
1. A display panel substrate that constitutes a display panel, comprising:
- an insulating substrate;
first conductive wires formed on the insulating substrate;
a piezoelectric film formed on the first conductive wires and the insulating substrate so as to be at least in an effective display area of the insulating substrate;
second conductive wires intersecting with the first conductive wires via the piezoelectric film; and
an insulating film for protecting the first and second conductive wires and the piezoelectric film at least in the effective display area of the insulating substrate.

Abstract
A display panel substrate according to the present invention includes at least an insulating substrate, first conductive wires formed on the insulating substrate, a piezoelectric material film formed on the first conductive wires, second conductive wires intersecting with the first conductive wires, and a protecting film for protecting the first conductive wires, the second conductive wires, and the piezoelectric material film. The insulating film is formed at least in an area in an effective display area on the insulating substrate. The piezoelectric film is formed at least at an intersection of a first conductive wire and a second conductive wire. This makes it possible to provide a display panel substrate that allows integration of a touch panel function into a display panel without causing an increase in size of the display panel.
