ABSTRACT:
A flat display unit has a chassis combining a display panel and circuit boards for driving the display panel into a unit in which the display panel and the circuit boards are mounted on respective opposite surfaces of the chassis. The chassis is provided with a bank (i.e., sidewall) extending about the periphery of opposite main surfaces of the chassis including at least the surface on which the display panel is mounted, perpendicularly to that surface and surrounding the periphery of the display panel3, and hence protecting the display panel without requiring a protector, as is conventionally used during the processes of assembling, testing and transporting thereof. The chassis is also provided with through-holes and optionally with a cut-out, which are formed in the periphery of the chassis, for facilitating interconnections between the display panel and the circuit boards by flexible cables which pass therethrough.
