The present invention relates to a substrate treating device and, more specifically, to a device for discharging liquid droplets of liquid crystals, polyimide (PI), and color filters (CF) onto a substrate through an inkjet technique. The substrate treating device according to an embodiment of the present invention comprises: a substrate support member for supporting a substrate; a nozzle unit that includes one or more nozzles that spray a treating liquid onto the substrate that is supported by means of the substrate support member; and a discharge amount measuring unit for measuring the discharge amount of the treated liquid that is discharged from the nozzles. The discharge amount measuring unit comprises: a stage for providing a space in which the discharge amount of the treating liquid is measured; a discharge plate that is disposed in the stage and discharges the treating liquid; a photographing member that photographs an area to which the treating liquid is discharged from the discharge plate; and a calculator that calculates the discharge amount of the treating liquid from the image photographed by means of the photographing member. The stage has a fixing groove that is downwardly concave, and the discharge plate is disposed in the fixing groove. |
