Sometimes it is easy to forget what Potential and Field mean. Let's look at it in 3D to get a better idea. Potential is related to energy and Field is related to force. This visualization shows the positive charges as high hills and the negative charges as valleys. Imagine a positively charged particle placed at the top of the positive "hill". What is the direction of the Electric Field at this point ? In why direction will the particle move ? Hint: Imagine these hills and valleys as gravitational. For a positive charge (as we are inspecting), it works exactly the same way.
