A liquid crystal display module device includes a frame receiving a backlight assembly provided with optical sheets, a liquid crystal panel mounted onto the frame, a bottom case affixed to the frame, a top case enclosing edge portions of the liquid crystal panel and coupled to the bottom case, and a clip inserted into a first region of a coupled portion of the bottom case and the top case. Extending the E-plane sectoral flare is a twist-reflector tilted from one sidewall of the E-plane flare and a trans-reflector extending from another opposing sidewall of the E-plane flare. The hook member and the washer comprise co-operating locking ratchet elements for locking the fastener to the washer and thus preventing the fastener from loosening from the ceiling. A reliability value determination unit determines a reliability value for indicating the reliability of the determined relative velocity based on at least one of the group consisting of the detected interference signal, the determined relative velocity and a characteristic of the laser. A multiple-bit data string, M, is received in which M is of the form:. More specifically, the present invention relates to a goods-display self in which improved are the structure of unit shelves composed by combining end caps with both ends of fixed frames accommodating roller units and the structure of front and rear support frames combined with both ends of the unit shelves.
