Title:
POLYMER FILM AND COMMUNICATION BOARD
Document Type and Number:
WIPO Patent Application WO/2021/193186
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a polymer film having low anisotropy of linear expansion. The present invention also addresses the problem of providing a communication board having the polymer film. This polymer film contains a liquid crystal polymer, wherein, when the surface of the polymer film is observed under a crossed Nicol environment by a polarizing microscope, a plurality of bright parts are observed in the observation region, and the circle-equivalent diameter of the bright part has has the largest circle-equivalent diameter among the plurality of bright parts is 10 μm or less.
