A reinforcement-type polarizing optical film laminate is provided which can comprehensively solve the problems of polyenization, color loss and red discoloration from heating, and which can solve the problem of cracking in a polarizing film laminate. The reinforcement-type polarizing optical film laminate contains a polarizing film laminate which, in an x-y Cartesian coordinate system in which the x-axis is the iodine concentration in the polarizing film and the y-axis is the moisture content in the polarizing film laminate, has an iodine concentration and moisture content included in the area enclosed by: a first line segment that connects a first coordinate point at 7.0 wt% iodine concentration and 0.7 g/m2 moisture content and a second coordinate point at 2.2 wt% iodine concentration and 3.2 g/m2 moisture content; a second line segment that connects the second coordinate point and a third coordinate point at 2.2 wt% iodine concentration and 4.0 g/m2 moisture content; a third line segment that connects the
