An electronic device with two-dimensional sliding cover and a two-dimensional slide apparatus are disclosed. The two-dimensional slide apparatus includes a first member, a second member, a third member and a first torque-retaining assembly. The second member is movable along a first direction in relation to the first member. The third member is movable between a first position and a second position along a second direction in relation to the second member, with a first central position therebetween. The first torque-retaining assembly is disposed between the second member and the third member. When the third member moves from the first position or the second position to the first central position by an external force, the first torque-retaining assembly generates torque, driving the third member from the first central position to the first position or the second position.
