PURPOSE: An electrofluid display device is provided to supply different voltages to dual channels by forming a thin film transistor on a first substrate only, supplying a voltage to a pixel electrode on the first substrate, and supplying a fixed amount of common voltage to a second substrate without forming a separate thin film transistor on the second substrate. CONSTITUTION: A thin film transistor (TFT) is formed in each pixel domain on a first substrate (10). First and second channels (41,42) are formed between the first substrate and a second substrate (30), and converts the hydrophobic property into the hydrophilic property according to supply of a voltage. A reflection layer (52) reflects the incident light from outside. A colored solution (62) and transparent oil (64) are filled in the first and second channels, and spread to the first channel or the second channel according to supply of a voltage. A pixel voltage changed through the TFT and a second common voltage with a predetermined size are supplied to the first channel. A first common voltage and the second common voltage having different predetermined sizes are supplied to the second channel. |
