Abstract

The present invention provides a liquid crystal display device and a manufacturing method thereof. The liquid crystal display device uses a quantum rod orientation layer (2) to conduct parallel alignment of a quantum rod layer (3) so that the aligned quantum rod layer (3) may replace a conventional lower polarizer. The liquid crystal display device manufacturing method applies an inclined vapor deposition process to form a quantum rod orientation layer (2). The quantum rod orientation layer (2) includes a plurality of grooves (21) that has an extension direction substantially perpendicular to a transmission axis direction of an upper polarizer (7). A quantum rod layer (3) is then formed on the quantum rod orientation layer (2). The quantum rod layer (3) so formed includes a plurality of quantum rods (31) that has a long axis direction substantially parallel to the extension direction of the grooves (21), namely parallel alignment of the quantum rod layer (3). The aligned quantum rod layer (3) may replace a conventional lower polarizer to improve light transmission rate and utilization of backlighting, increasing displaying brightness and reducing manufacturing cost.
