Abstract: Disclosed is a chip-on-glass type liquid crystal display (LCD). The LCD is directed to provide a construction in a way that, while each wiring for supplying driver circuits with a driving voltage is directly formed on an LCD panel through application of COG (Chip-On-Glass) technology for producing TFT-LCD, even though the wirings are connected in series between the driver circuits, the driving voltage capable of normally operating the driver circuits is supplied to all driver circuits. To this end, in consideration of a voltage drop at the panel wiring, by increasing and outputting a driving voltage, the driving voltage inputted into an nth driver circuit is made to be equal to the driving voltage inputted into an (n+1)th driver circuit.

Abstract: Disclosed is a mode-filtering and mode-selecting method in a multi-mode waveguide, and a waveguide amplifier, a semiconductor laser, and a VCSEL using the method. These optical elements include a cladding region that has a periodically changed refractive-index structure, thereby obtaining a mode-filtering or mode-selecting function, which in turn allows only a single mode in the transverse direction to propagate along the waveguide. By forming the periodic index-variation structure, the EDF, the semiconductor laser, and the VCSEL achieve a single mode operation although the cross-sectional area is much larger than that of the prior art, consequently realizing a high-performance or high-power single-mode amplifier and laser.
