Patent ID: 8780063

Claim:
A touch display panel, comprising: a display unit comprising: a first base substrate comprising a plurality of pixel electrodes; a second base substrate comprising a common electrode disposed on a first face of the second base substrate, the first face facing the first base substrate; and an electrophoretic layer disposed between the pixel electrodes and the common electrode, the electrophoretic layer comprising a plurality of electrophoretic balls; and a touch unit comprising: a color filter layer comprising a plurality of color filters; a first electrode part comprising first electrodes and first connecting electrodes on a second face of the second base substrate, the first electrodes being light blocking electrodes on a display area of the display unit being located at a boundary between a first color filter and a second color filter, the second color filter being different from the first color filter in color, the first connecting electrodes electrically connecting end portions of the first electrodes on the display area; a first line electrode disposed on a peripheral area of the display unit adjacent to the display area, the first line electrode being electrically connected to one of the first connecting electrodes, the first line electrode being thicker than the first electrodes; and a third base substrate comprising a second electrode part extending along a direction crossing the first electrodes, wherein the first electrodes, the first connecting electrodes and the first line electrode comprise a same material as each other.
