This paper noted the reflective characteristics on the micro grooves prepared on thin film, in order to control of the molecular alignment of LCD. The authors presented the new system of the opto-electronic property of the surface with fine structure. Micro grooves with fine pitch were cut by diamond cutter under the condition of small pitch(in micron order), small depth(about 500 nanometer)and extremely smooth surface(in manometer order). Repeatability of pitch of the grooves was in order of 0.08 μm(80 nm). The reflective distribution was researched under the condition on the tilt angle, pitch, randomness of the pitch and bulk materials. It was noted that fine structure of the micro grooves was strongly affected to the alignment of micro cell, that was to say, the molecular rotation and mobility of the liquid crystal. Ultra fine micro grooves prepared by Ruling Engine was usuful to standardization on the reflective characteristics, or opto-electronic characteristics.
