A portable display panel comprising:
- a liquid crystal display panel for displaying images;
- a backlight assembly including a light source for supplying light to the liquid crystal display panel;
- a bottom chassis for receiving the backlight assembly;
- a first printed circuit board for controlling the liquid crystal display panel and the light source, the first printed circuit board including a ground copper film;
- and
- a second printed circuit board connected to the first printed circuit board and an external drive circuit,
- wherein the first printed circuit board has an integral protrusion extending from a first side at a periphery of the first printed circuit board, the ground copper film exposed at an end of the protrusion, wherein the exposed ground copper film at the end of the protrusion is electrically connected to the bottom chassis.
