A power supply mounting apparatus includes a chassis (40), a mounting board (20) attached to the power supply, and a mounting bracket (30). The chassis includes a rear panel (50) with an opening (52), and first and second side panels (50, 70). The mounting board forms a pair of mounting hooks (25) at each side thereof. The mounting bracket includes two mounting portions (31, 32) and a connecting portion (33). Each mounting portion defines slits (35) and locking holes (36). The rear panel forms catches slidably engaging in the locking holes. After the power supply slides in the chassis with the mounting hooks extending in the corresponding slits, the mounting bracket is moved horizontally so that the hooks hook the rear panel. The second side panel is attached to the chassis to prevent the mounting bracket from leaving the chassis.

An exemplary liquid crystal panel (400) includes a first substrate (401) having a common electrode layer (429), a second substrate (402) parallel to the first substrate, and a liquid crystal layer (403) between the first and second substrates. The liquid crystal layer defines an active area (406) thereat. The second substrate includes common lines (440). Electrical coupling elements are disposed at the active area, so as to electrically couple the common electrode layer to the common lines.

A multi-domain IPS (in-plane switching) liquid crystal display (20) includes a first substrate (201), a second substrate (202), liquid crystal molecules (203) filled between the first and second substrates, and gate lines (211) and data lines (212) formed on the first substrate. The gate lines and data lines define pixel regions arranged in a matrix. Each pixel region includes pixel electrodes (233), common electrodes (243), and a TFT (thin film transistor) (220). The pixel electrodes and the common electrodes have a same curved shape with at least two different bend portions, and are uniformly spaced apart from each other. Therefore the electric field generated by them is a smooth continuum of multiple domains, and the visual performance at various different viewing angles is equally good. Because the pixel and common electrodes do not have sharp bends, disclination is avoided. Therefore the IPS liquid crystal display has a high contrast ratio.
