TOUCH DISPLAY DEVICE

A touch display device, relating to the technical field of display, and capable of reducing interference between signals and reducing production costs. The touch display device comprises a touch display module, a flexible printed board, and a touch chip. The flexible printed board is electrically connected to the touch display module, and comprises a first flexible substrate, a first metal pattern layer, a second metal pattern layer, and a metal shielding layer. The first metal pattern layer comprises a plurality of first touch wires. The second metal pattern layer comprises a plurality of data wires. The metal shielding layer is located between the first flexible substrate and the first metal pattern layer. A ratio of the longitudinal length of the metal shielding layer to the longitudinal length of the flexible printed board ranges from 20% to 40%. A vertical projection of the first metal pattern layer on the first flexible substrate and a vertical projection of the second metal pattern layer on the first flexible substrate have an overlapping region; and a vertical projection of the metal shielding layer on the first flexible substrate at least covers the overlapping region. The width of the first touch wires is greater than the width of the electrode leads.
