摘要：A display device includes a display panel, a gate driving circuit, a data driving circuit, and a storage driving circuit. The storage driving circuit includes a plurality of stages to apply a plurality of storage voltages, which are inverted in every frame, to the storage lines, respectively. A kth stage of the stages includes a counter charging part, a boosting part and a holding part. The counter charging part applies a first driving voltage to a kth storage line based on a kth gate signal. The boosting part applies a second driving voltage to the kth storage line based on a (k+2)th gate signal. The holding part applies a storage voltage to the kth storage line based on a (k+1)th gate signal during one frame. The level of the storage voltage corresponds to the second driving voltage.

主权项：1. A display device, comprising: a display panel comprising a plurality of gate lines, a plurality of data lines, and a plurality of storage lines, the storage lines extending in a direction substantially parallel to the gate lines; a gate driving circuit to apply a plurality of gate signals to the gate lines, respectively; a data driving circuit to apply a plurality of data voltages to the data lines, respectively; and a storage driving circuit comprising a plurality of stages to apply a plurality of storage voltages, which are inverted in every frame, to the storage lines, respectively, a kth stage of the stages comprising: a first voltage application unit to apply a first driving voltage to a kth storage line based on a kth gate signal; a second voltage application unit to apply a second driving voltage to the kth storage line based on a (k+2)th gate signal; and a third voltage application unit to apply a storage voltage to the kth storage line based on a (k+1)th gate signal, wherein ‘k’ is a natural number, wherein the third voltage application unit comprises: a first switching element to output a first switching voltage based on the (k+1)th gate signal; a second switching element to output a second switching voltage based on the (k+1)th gate signal; a third switching element to output a first storage voltage to the kth storage line based on the first switching voltage; a fourth switching element to output a second storage voltage to the kth storage line based on the second switching voltage; a first capacitor to be charged with the first switching voltage to maintain an on/off state of the third switching element during the one frame; and a second capacitor to be charged with the second switching voltage to maintain an on/off state of the fourth switching element during the one frame.
