Document Type and Number:
WIPO Patent Application WO/2019/221455
Kind Code:
A1
Abstract:
A pressure sensor according to embodiments of the present invention comprises: a first substrate; a first electrode layer comprising a plurality of sensing electrode patterns arranged on the first substrate and separated from each other and first wirings which are respectively connected to and extend from the sensing electrode patterns; an insulating layer on the first substrate and at least partially covering the first wirings; and a second electrode layer arranged so as to face the first electrode layer and provided as a common electrode for the plurality of sensing electrode patterns. A thin pressure sensor having improved flatness through the second electrode layer and reduced signal interference through the insulating layer may be implemented.
