PROBLEM TO BE SOLVED: To surely transfer a start signal STH among cascaded data-side drivers even when an electronic device performs a high-speed operation. SOLUTION: When data-side drivers 40 are cascaded, since a receiver 44 for inputting the start signal of the data-side driver 40 of the first stage is constituted as a CMADS (current mode advanced differential signaling) interface circuit with a transmitter for outputting the start signal of a controller and circuits for bypassing receivers 44 of data-side drivers 40 of the next stage and succeeding stages are constituted as CMOS (complementary metal-oxide semiconductor) interface circuits with buffers 43 of data-side drivers of respective preceding stages by changeover switches 45 which are included in receivers 44 of data-side drivers 40, the delay of the start signal in the cascade connection can be made smaller than that in the CMADS interface circuit and it is possible to read the start signal STH normally at the rising edge of a clock signal CLK in data-side drivers 40 of the side of the succeeding stages.
