Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polarizing plate through which light does not break even when the polarizing plate is used at high temperature, for example, in the open air or even when the polarizing plate warmed by the heat generated from a backlight is viewed from the oblique direction and to provide an IPS (in-plane switching) mode liquid crystal display apparatus using the polarizing plate. SOLUTION: The polarizing plate is obtained by layering, at the least, a first protective film, a polarizing film and a second protective film in this order. The second protective film is composed, at the least, of a transparent film and an optically anisotropic layer containing a substantially vertically-oriented polymerizable liquid crystal compound. The first protective film has, at the least, a void holding layer of ≥30% void ratio on the surface opposite to the polarizing film-layered surface. COPYRIGHT: (C)2010,JPO&INPIT
