摘要:
To solve simultaneously the problems of scale-shaped unevenness (scale unevenness) and a raise (bead) in the edge of a substrate coming into existence upon application of a photosensitive resin composition onto particularly a large-size substrate, a silicone oil represented by the general formula (1) below is incorporated into a photosensitive resin composition containing an alkali-soluble resin such as novolak resin and a photosensitizer having a quinonediazide group in an amount of 50 to 5,000 ppm based on the total solids content of a photosensitive resin composition. Wherein R1, R2, R3, R4, R5 and R6 independently represent a hydrogen atom, a hydroxyl group, a C1-4 alkyl group or an aryl group, m is an integer of 1 to 40, and n is an integer of 1 to 40.

The conventional mirror shows only a reflected image. For example, a user who looks at the same mirror at a face-washing place at home every day can see only the similar reflected image. The present invention provides an information displaying device capable of displaying information which can be displayed by the primary function and information which can be displayed by another function on the same display unit. The information displaying device includes a projector for projecting video, a display unit for displaying the video, and a diffusion layer attached to the display unit for diffusing the light projected from the projector. The display unit displays not only a reflected image on the front side of display surface but also video and characters projected by the projector from the rear side of the display unit.
