The invention discloses a line recognition and display device. The device comprises an array substrate, a line bearing plate opposite to the array substrate, light-sensing units, condensing lenses and shading parts, wherein the light-sensing units in at least part of pixel areas are located on the array substrate, the condensing lenses correspond to the light-sensing unit one to one and are located at the sides, facing the line bearing plate, of the light-sensing units, and the shading parts correspond to the condensing lenses one to one and are located between the condensing lenses and the corresponding light-sensing units. When a finger or palm makes contact with the line bearing plate, light which is reflected by the finger or palm and irradiated to the condensing lenses is gathered in the main optical axis direction by means of the condensing lenses, but only part of light meeting specific conditions can irradiate to the light-sensing units because of light-pervious holes, and accordingly the light-sensing units only collect light in the specific transmission direction. Thus, no matter how far the light-sensing units are from the upper surface of the line bearing plate, optical crosstalk can be reduced.
