Title:
DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/039675
Kind Code:
A1
Abstract:
A cover panel (13) comprises a first surface (F1) to be subject to pointing by a pointing body (900), and a second surface (F2) which is opposite to the first surface (F1). A position detection layer (LD) above the second surface (F2) has a distance t from the first surface (F1). The position detection layer (LD) comprises first electrodes (21) and second electrodes (31). A display panel (2) comprises a pressure detection electrode (40) which faces the position detection layer (LD) with a gap (GP) therebetween. Given that a length s is defined as the maximum length of line segments which, in plan view, pass through arbitrary points in gaps between the first electrodes (21) and the second electrodes (31) and which join the first electrodes (21) and the second electrodes (31) at the shortest distances, an inequality t>s/2 is satisfied.
