Document Type and Number:
Japanese Patent JP6402625
Kind Code:
B2
Abstract:
The present invention relates to an optical film production method for suppressing the remaining of air bubbles in microlenses, and in particular, an optical film production method comprising a step of rotating a roll die (51) having an outer circumferential surface having a plurality of concave-shaped microlens transfer portions disposed thereon and running a substrate (22) in the rotation direction; a step of supplying an active energy ray-curable composition ² onto a coating roll (53) disposed to be adjacent to the outer circumferential surface of the roll die, flattening the active energy ray-curable composition ² by a flattening means, coating the flattened active energy ray-curable composition ² on the outer circumferential surface of the roll die; a step of supplying an active energy ray-curable composition ± on the substrate and coating the active energy ray-curable composition ± on a surface of the substrate; a step of associating the compositions ± and ² at an association portion between the roll die and the substrate to form a liquid pool; and a step of irradiating a region between the outer circumferential surface of the roll die and the surface of the substrate with an active energy ray in a state in which the compositions ± and ² are sandwiched between the outer circumferential surface of the roll die and the surface of the substrate to cure the compositions ± and ².
