Angel Lateral Stability

I've been trying to understand how dihedral contributes to lateral stability, the explanation is basically the same in
all texts I've ]managed to find. they go on to explain how the roll will incline the lift vector and the horizontal component will cause a sideslip, then the the relative airflow will be coming from the side oppsite to the direction of the sideslip. And because of dihedral, the angle of attack of the lower wing will be higher than that of the upper wing, which will cause the ac to roll to a laterally level position. Now the part i am having difficulty picturing, is how dihedral was the cause for a different AOA on both wings.

thanx . . .
