Abstract
An electrophoretic display panel includes a first substrate, a second substrate, a partition wall, first electrodes, a second electrode, a dispersant, positively-charged particles, negatively-charged particles, weakly-charged particles, switching thin film transistors, scanning lines, and signal lines. Pixel spaces are surrounded by the partition wall, the first substrate and the second substrate. Two of the first electrodes are formed on the first substrate in each pixel. The second electrode facing the first electrodes is formed on the second substrate. The dispersant with the positively-charged particles, the negatively-charged particles, and weakly-charged particles is contained in the pixel spaces. The switching thin film transistors are connected to the first electrode, and the signal line. The scanning lines supply scanning signals to gate electrodes of the switching thin film transistors. The signal lines input a data signal to the switching thin film transistors.
