Shield grants a cover bonus, which is effective against touch attacks.Drew said:What about the Shield spell?
Touch attacks come in two types: melee touch attacks and ranged touch attacks. A combatant can score critical hits with either type of attack. A combatant's opponent's AC against a touch attack does not include any armor bonus, shield bonus, or natural armor bonus. The target's size modifier, Dexterity modifier, and deflection bonus (if any) all apply normally.
