A defective display is obviated by preventing the intrusion of a foreign substance in a gap defined between a constitutional member, such as an upper frame, an intermediate frame, a backlight device or the like, and a display panel and by suppressing the application of a stress to the display panel. A shaped elastic member is interposed between a liquid crystal display panel and a mold of a backlight device. One longitudinal side surface of the shaped elastic member is fixedly mounted on the backlight device and the other longitudinal side surface of the shaped elastic member is non-fixedly mounted on the liquid crystal display panel, such that the other longitudinal side surface is always brought into contact with the liquid crystal display panel to prevent the generation of a gap therebetween.

Multiple alignment patterns, each composed of first and second alignment pattern elements printed by forward and backward movements of a print head, respectively, are formed while the relative printing positions of the two elements are shifted. From optical characteristics data thereof, whether the data is influenced by a disturbance is determined. When the data is determined to be less influenced by the disturbance and therefore to be reliable, an adjusting value for aligning positions in printing in reciprocal movements is calculated by use of: data with the smallest relative printing position misalignment between the first and second alignment pattern elements; and data of optical characteristics close to the data. When the data is largely influence by the disturbance, a range of shifting of relative position is widened than that of the data less influenced by the disturbance so that more data pieces are used to obtain the adjusting value.
