Abstract

A color filter substrate ( 2 ), a liquid crystal module and a display device are disclosed. The color filter substrate includes a touch flexible printed circuit binding area ( 3 ) for binding a touch flexible printed circuit; and a black matrix area ( 4 ) light shielding; the touch flexible printed circuit binding area ( 3 ) and the black matrix area ( 4 ) are two areas separate from each other and have no overlapping or partially overlapping parts therebetween; and a bottom of the touch flexible printed circuit binding area ( 3 ) is transparent. The color filter substrate ( 2 ), the liquid crystal module and the display device enable the binding conditions and the state of conducting particles to be monitored from backside, so that product yield is improved and accident rate is reduced.
