Abstract
An electrophoretic display device includes a first substrate having a display region and a non-display region at a periphery of the display region, the display region including a pixel region; gate and data lines on the first substrate and in the display region, the gate and data lines crossing each other to define the pixel region; a gate link line connected to the gate line and positioned in the non-display region; a thin film transistor connected to the gate and data lines and positioned in the pixel region, the thin film transistor including a gate electrode, a gate insulating layer, a semiconductor layer, a source electrode and a drain electrode; a passivation layer of an organic insulating material over the thin film transistor and in the display region, the passivation layer having a first thickness and including a drain contact hole exposing the drain electrode; a buffer pattern formed of the same material and having the same thickness as the passivation layer, the buffer pattern positioned in the non-display region; a pixel electrode positioned in the pixel region and on the passivation layer, the pixel electrode connected to the drain electrode through the drain contact hole; and an electrophoretic film on the pixel electrode and covering an entire surface of the display region, an end of the electrophoretic film positioned on the buffer pattern.
