An electrophoresis device includes a pair of substrates, a plurality of pixel electrodes, and a common electrode formed on the pair of substrates, a liquid material formed by dispersing charged particles sealed between the pair of substrates and a driving circuit for applying a voltage to the pixel electrodes and the common electrode to generate an electric field therebetween. The semiconductor substrate between the source region and the drain region is selectively removed so as to form a recess for a gate electrode. A wall of the enclosed envelope is a gas-tight blocking layer. An input port may be intermediate and operably connected to the input voltage source and the activation transistor. The pixel structure includes a switching transistor, a driving transistor, a capacitor, a light emitting diode and a reset transistor. In a two-high stack, address lines of the constituent ICs are interconnected, while the data lines of the respective ICs are concatenated to double the data path width of the stack relative to the data path width of the constituent ICs.
