Abstract: A method for manufacturing a light guide plate includes the following steps: (12) providing a photo mask having certain patterns of dots associated therewith; (16) using the photo mask to form an imprinting stamper; and (18) using the imprinting stamper to imprint an original light guide plate, thereby forming a light guide plate having the certain pattern of dots. The dots on the light guide plate manufactured by the present method are fine (i.e., with respect to microstructure), due to a high precision of the imprinting stamper. This precision can result in substantial or even entire uniformity of emitted light beams from the light guide plate. Thus, liquid crystal display devices adopting the light guide plate can provide satisfactory display quality. Therefore, the present method can be advantageously applied in manufacturing the light guide plate used in the liquid crystal display devices.

Abstract: A display device (30) includes a display panel (32) and a backlight module (31). The display panel includes a transparent anode layer (325), a transparent cathode layer (323), and a layer of phase-change material (324) sandwiched therebetween. The backlight module is arranged adjacent the display panel. The display device utilizes a phase-change material to serve as a light switch and can fully make use of the available light emitted from the backlight module for display purposes, thereby permitting a high utilization efficiency of light to be realized. In addition, the function of a light switch is achieved by the electron transition occurring in the phase-change material. Because the time of such an electron transition is very short, the response time of the display panel is thus decreased.

This ensures relatively little process in the production line. Therefore, the prism sheet can be advantageously applied in backlight modules (5) of liquid crystal display devices.
