A system for displaying information for quality control of a component-mounted substrate that is produced in a production line, at least one process performed in the production line of the component-mounted substrate being adopted as a targeted process, and the system being adapted to use measured data obtained in an inspection performed after the targeted process, the system comprising: an attribute storage unit for storing, as an attribute of a measurement target section, a combination of identification information of constituent elements related to each of a plurality of measurement target sections included in one component-mounted substrate; an attribute input unit for inputting, as an attribute of a substrate, information representing a production condition of the targeted process performed on each of the substrates; a measured data input unit for inputting the measured data obtained for each of the measurement target sections of the substrates in the inspection of the targeted process; a display information storage unit for storing display information in which numerical values included in the measured data are classified into a preferable numerical range and a non-preferable numerical range, the non-preferable numerical range being displayed in a color or shade different from that of the preferable numerical range; characterised by a map image generation unit for generating a two-dimensional map image representing a distribution of the measured data upon setting a two-dimensional area and setting the color or shade to corresponding positions on the two-dimensional area including a first axis and a second axis, in which the identification information of the constituent elements stored in the attribute storage unit are arranged into a hierarchical structure based on relationship between the constituent elements, the first axis being arranged with the measurement target sections associated with said arrangement of the identification information of the constituent elements, the substrates to be displayed being arranged into an order of the substrates subjected to the targeted process, and the second axis being arranged with the identification information of the production conditions corresponding to the substrates in accordance with said order, the color or shade being obtained by applying the display information to the measured data that are input for each of the measurement target sections of the substrates; and a display control unit for displaying, on a monitor apparatus, the two-dimensional map image generated by the map image generation unit. an attribute storage unit for storing, as an attribute of a measurement target section, a combination of identification information of constituent elements related to each of a plurality of measurement target sections included in one component-mounted substrate; an attribute input unit for inputting, as an attribute of a substrate, information representing a production condition of the targeted process performed on each of the substrates; a measured data input unit for inputting the measured data obtained for each of the measurement target sections of the substrates in the inspection of the targeted process; a display information storage unit for storing display information in which numerical values included in the measured data are classified into a preferable numerical range and a non-preferable numerical range, the non-preferable numerical range being displayed in a color or shade different from that of the preferable numerical range;
