In a conducting plate-like in a capacitor, the electric field lines are perpendicular to the plates and the equipotential lines are parallel to the plates. The illustration below shows the electric field of a positive point charge.The electric field is fixed away from the charge and potential is positive at any set distance from the charge.
In each plate of the capacitor, there are many negative and positive charges, but the number of negative charges balances the number of positive charges, so that there is no net charge, and therefore no electric field between the plates.
The capacitance is an internist propriety of any configuration of two conductors when placed next to each others. The capacitor does not need to be charged (holding a charge Q with a potential difference ΔV across the conductors) for its capacitance to exist: also when a capacitor is not charged it does have a capacitance!
The electric field is said to be the gradient (as in grade or slope) of the electric potential.

In general if a conductor of capacity C is charged to a potential V by giving it a charge q, then (i) When a dielectric slab is inserted between the plates of a charged capacitor, with battery connected to its plates. Then, the capacitance becomes K (dielectric constant) times and energy stored in the capacitor becomes KU 0.
A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates. This is known as edge effects, and the non-uniform fields near the edge are called the fringing fields.
