A display device having a display array of mxn display elements driven by a static shift register having mxn stages respectively corresponding to row and column designations of the display elements. The column lines of the display element array are driven by a first output of the m stages. At the same time, pixel data are supplied to the shift register in accordance with a binary level of an externally supplied select signal. Alternatively, the shift register is shifted in a recursive manner. The row lines of the display element array are scanned in accordance with a count of a clock signal. Select signal lines and clock signal lines are respectively aligned along the row and column directions of a unit panel when plural display arrays as described above are arranged in a matrix form to provide a large-screen display unit. The lines of each display array are sequentially driven in accordance with the supply pattern of the select and clock signals from a corresponding unit driver. The shift register arrangement decreases the number of connections or wirings between a module driver and the display element array and simplifies the circuit arrangement of the module driver. |
