Abstract: 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 point and a second point; a second line segment connecting the second point and a third point; a third line segment connecting the third point and a fourth point; a fourth line segment connecting the fourth point and a fifth point; and a fifth line segment connecting the first point and the fifth point, wherein the reinforced film laminate has a breaking strength in a MD direction of 135 N/10 mm or more.
