Zusammenfassung:	The present invention addresses the problem of providing: an optically anisotropic layer capable of producing an image display device in which the occurrence of light leakage on the oblique side can be suppressed; an optical film having the optically anisotropic layer; a polarizing plate; and an image display device. This optically anisotropic layer is obtained by curing a polymerizable liquid crystal composition containing a prescribed rod-like liquid crystal compound and a monofunctional compound, and immobilizing the orientation state of the rod-like liquid crystal compound, the number of atoms a1 of the rod-like liquid crystal compound and the number of atoms a2 of the monofunctional compound satisfy the relationship of formula (1), and the rod-like liquid crystal compound is immobilized in a state of being oriented perpendicular to the main surface of the optically anisotropic layer (formula (1): 0.2 < a2/a1 < = 0.68. 本发明的课题在于提供一种能够制作可抑制斜侧漏光的产生的图像显示装置的光学各向异性层以及具有光学各向异性层的光学膜、偏振片及图像显示装置。本发明的光学各向异性层为使包含规定的棒
