Provided is a reinforced polarizing film laminate capable of comprehensively solving the problems of polyene formation, color loss and heat-caused red discoloration, and solving a crack problem in a polarizing film laminate. The reinforced polarizing optical film laminate comprises a polarizing film laminate containing an iodine concentration for the polarizing film and a water content for the polarizing film laminate which fall within a region surrounded, in an x-y orthogonal coordinate system in which the iodine concentration of the polarizing film is plotted on the x-axis, and the water content of the polarizing film laminate is plotted on the y-axis, by: a first line segment connecting a first coordinate point at which the iodine concentration is 7.0 wt% and the water content is 0.7 g/m2, and a second coordinate point at which the iodine concentration is 2.2 wt% and the water content is 3.2 g/m2; a second line segment connecting the second coordinate point, and a third coordinate point at which the iodine
