PROBLEM TO BE SOLVED: To provide light guide plates connected in series in which even if either reflection or diffusion occurs at their cooperated surfaces, it can be made inconspicuous.SOLUTION: This invention relates to a sequential connected light guide plate 100 in which light guide plates having light incident from at least one side surface and mainly ejected to a principal surface are connected in series, adjoining one light guide plate 10a opposing against the other light guide plate 10b has a front surface and a lower surface formed to have a lower step than the front surface. The other opposing surface of one light guide plate of the other light guide plate 10b has a form that can be fitted to one side surface. In turn, a principal plane of the light guide plate is formed with diffusion dots 20 at positions corresponding to the lower surface when it is visually confirmed from the principal plane side.SELECTED DRAWING: Figure 1 |
