Abstract: The present disclosure provides a line recognition module, a fabricating method thereof and a display device. A better collimating effect may be achieved only by fabricating an optical sensing structure on a substrate in the line recognition module and then directly fabricating at least two light shading layers and a light transmitting layer with relatively simple structures, and the device structure is light and thin, which can reduce the difficulty of processing the device. The problem that the yield is affected due to blistering caused by attaching a collimating structure to the line recognition module with use of an optically clear adhesive (OCA) is avoided. Moreover, since film layers are fabricated directly on the optical sensing structure to form the collimating structure, fabrication of the collimating structure may be accomplished by using a generic device for fabrication of the film layers on an array substrate without adding new fabrication equipment.
