PROBLEM TO BE SOLVED: To prevent damages from occurring in a flexible wiring board, at contraction of a drive board after heating by suppressing the thermal expansion of the drive board, by heating at connection work of the drive board to the flexible wiring board. SOLUTION: In this drive board connected to a display panel via the flexible wiring board, connecting land parts for connecting one-end side of the flexible wiring board thereto by thermocompression bonding, along the longitudinal one-side edge of a surface of a board comprising a printed wiring board, and non-connecting land parts are arranged alternately along the longitudinal direction; thermal expansion-absorbing through-holes are formed on the non-connecting land parts by penetrating the board, or the thermal expansion-absorbing recessed parts are formed on the surfaces of the non-connecting land parts.
