The present invention provides a method of alignment between sheet materials, a method of alignment, a substrate assembling method, and an aligning apparatus, which are capable of easily and surely performing highly accurate alignment and suppressing a reduction in material yield. After alignment performed based on a band-like light as a reference, alignment is performed based on a joint of a condenser lens portion of a lenticular lens as a reference. More specifically, the deviation of a liquid crystal display cell in a rotational direction is corrected by using a light emitted from a light source and condensed to be band-like at the lenticular lens as a reference. Subsequently, by changing a depth of focus of a microscope, measurement is performed for positions of a black matrix of the liquid crystal display cell and the- joint of the condenser lens portion of the lenticular lens. Then, based on the result of the measurement, horizontal alignment is performed between the liquid crystal display cell and the lenticular lens.
