A flexible EL device comprises a substrate, which is made of highly polymerized synthetic rubber, polyurethane, or silicon rubber, a conductive layer, a dielectric layer, a fluorescent layer, a transparent conductive layer, and a polymer protection film layer. Due to the high flexibility of the substrate, the flexibility of the flexible EL device according to the present invention is higher than the conventional EL device using PET, and therefore, the durability of the flexible EL device under mechanical impact is improved. As a result, the flexible EL device is not damaged when physical impacts are applied to the flexible EL device. Furthermore, noise is prevented or reduced by simply changing the structure of the flexible EL device and adding material layers, and therefore, electric and physical properties of the flexible EL device are improved. The flexible EL device is applicable to EL dome sheets or EL keypads.

An apparatus and method for allocating a bandwidth for up-stream data transmission to a plurality of Optical Network Units (ONUs) in an Ethernet Passive Optical Access Network (EPON) in which the ONUs are connected to a single Optical Line Terminal (OLT) are disclosed. The bandwidth allocation method for guaranteeing a Quality of Service (QoS) in the EPON includes the steps of: a) classifying up-stream data to be transmitted from a plurality of Optical Network Units (ONUs) of the EPON to an Optical Line Terminal (OLT) into a plurality of classes according to predetermined data priority information, and requesting bandwidths required for individual classes from the OLT; b) allowing the OLT to perform a bandwidth distribution process according to bandwidth requirement quantities of individual classes using weights pre-assigned to individual classes; and c) allowing the OLT to distribute a residual bandwidth acquired after the bandwidth distribution process is performed from among an available total up-stream bandwidth to the ONUs.

A method for manufacturing an LCD device includes preparing first and second substrates and dispensing liquid crystal on the first substrate. A plurality of column spacers are formed on the second substrate, and a seal pattern is formed on the second substrate. The second substrate is inversed and the first and second substrates are bonded to each other to form an LCD panel having a first height (h1) corresponding to a cell gap between the first and second substrates. Pressure is applied to the rear surfaces of the first or second substrates so as to change the cell gap to a second height (h2) smaller than the first height (h2
