You recognize a greater performance benefit with a movie clip that would have many
transparent regions if
opaqueBackground were not set.
Note:The opaque background region is not matched in a
hitTest() method that has the
shapeFlag parameter set to true.

Example
The following example creates a triangle outline and sets the
opaqueBackground property to
a specific color:
var triangle:MovieClip = this.createEmptyMovieClip("triangle",
this.getNextHighestDepth());
triangle._x = triangle._y = 50;
triangle.lineStyle(3, 0xFFCC00);
triangle.lineTo(0, 30);
triangle.lineTo(50, 0);
triangle.lineTo(0, 0);
triangle.endFill();
triangle.opaqueBackground = 0xCCCCCC;
If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth() method, which is
used in this example.

specify a relative path to movie clips or objects that are above the current movie clip or object.
You can use
_parent to move up multiple levels in the display list, as in the following code:
this._parent._parent._alpha = 20;
