Abstract

An electrooptic display device includes a TFT substrate, a touch panel superimposed and placed on the TFT substrate, a circuit board spaced apart from the TFT substrate and the touch panel, one side of the circuit board facing the TFT substrate and the touch panel, a plurality of first FPCs each including one end electrically connected to one side of the TFT substrate, and the other end electrically connected to one side of the circuit board, and a second FPC that is electrically connected to the touch panel and extends in parallel to the first FPCs. The circuit board includes a cutout in a portion overlapping the second FPC on one side of the circuit board.

Claims (33)
