When making light-emitting component 23 in dark local luminous, come the light of self-emission device 23 to enter light guide plate 24 from the side, this light that enters in light guide plate 24 surfacewise direction be guided.When this light was guided first illumination section 26 of light guide plate 24, this light that is guided was by jog 28 scatterings, and shone the upper surface of light guide plate 24.And, the light that leaks from the lower face side of the light guide plate 24 upwards reflection of plate 25 that is reflected.Thus, carry out surface emitting from whole first illumination section 26 of light guide plate 24, and can illuminate dial plate 13 from lower face side by this surface emitting.And, because the light that surface emitting produces passes dial plate 13, also can illuminate the pointer 15 that above dial plate 13, moves.Therefore, even in the place of dark also can come recognition time by dial plate 13 and pointer 15.
When being in dark place, when coming the light of self-emission device 23 to be guided second illumination section 27 of light guide plate 24, this light that is guided is from the reflecting surface 29a of each prism 29 of the second illumination section 27 lower face side reflection towards light guide plate 24.Therefore, carry out surface emitting from whole second illumination section 27 of light guide plate 24, and the rayed of this kind surface emitting is in the entire upper surface of the liquid crystal display cells 10 of second illumination section, 27 downsides.Thus, can roughly illuminate whole liquid crystal display cells 10 equably.Therefore,, also can be identified on the liquid crystal display cells 10 information that shows, as the time etc. even in the place of dark.
According to this wrist-watch, when the place in dark makes the 23 emission light time of light-emitting component, light enters light guide plate 24 from the side, and is guided along the surface direction of light guide plate 24, and the light that is guided first illumination section 26 of light guide plate 24 shines towards the upper surface side of the light guide plate 24 of first illumination section 26.Thus, carry out surface emitting from first illumination section 26, thereby illuminate the upper surface side of light guide plate 24.The light that is guided second illumination section 27 of light guide plate 24 shines towards the lower face side of the light guide plate 24 of second illumination section 27.Thus, carry out surface emitting from second illumination section 27, thereby illuminate the lower face side of light guide plate 24.Therefore, the upper and lower face side of light guide plate 24 can be illuminated by a light guide plate 24.Thereby, can illuminate the dial plate 13 and the pointer 15 of expression first display unit of every side of the upper and lower face side that is arranged in light guide plate 24 and the liquid crystal display cells 10 of representing second display unit well, and can recognition time in bright place and dark place.
In this wrist-watch, owing to can illuminate the upper and lower face side of light guide plate 24 with a light guide plate 24, even therefore place liquid crystal display cells 10, also need on the lower surface of liquid crystal display cells 10, not use the planar backlight device, as EL element (electroluminescent cell) at light guide plate 24 downsides.Like this, can be used as the table assembly 3 that an integral body realizes thin shape and saves the space, so that this wrist-watch can be small size and thin shape as a whole.Since liquid crystal display cells 10 can with second illumination section, 27 placed adjacent of light guide plate 24, therefore can suppress because light causes that in the refraction on the light guide plate 24 soft edge of the information of demonstration on liquid crystal display cells 10 is unclear.Therefore, can clearly be identified in the information that shows on the liquid crystal display cells 10.

In light guide plate 24, from light-emitting component 23 enter light guide plate 24 and surfacewise direction guiding light hardly from the reflecting surface 30a reflection of prism 130 but surfacewise direction directly guide.Therefore, side surface reflecting part 131 is arranged on the side surface of light guide plate 24.As shown in figure 46, side surface reflecting part 131 be arranged on from 12 o'clock on the side surface of the light guide plate 24 at 9 o'clock to 6 o'clock.Shown in Figure 46 and 48, when the light that comes self-emission device 23 was guided in light guide plate 24 and arrived the side of light guide plate 24, this light was to the internal reflection of light guide plate 24.In this case, because light guide plate 24 forms roughly plate-like, so side surface reflecting part 131 forms roughly semicircle arcuation on the side surface of light guide plate 24.Therefore, and the light that arrives light guide plate 24 inner from light-emitting component 23 directive light guide plate 24 is from the beam reflection of side surface reflecting part 131 as almost parallel.
According to this wrist-watch, as the 9th embodiment, in bright local exterior light irradiation pointer 15 and light guide plate 24, and this irradiates light passes light guide plate 24 irradiation dial plates 13, and via the opening portion 16 irradiating liquid crystal display elements 10 of dial plate 13.Like this, can pass through pointer 15 and dial plate 13 recognition times, and can discern the information that is presented on the liquid crystal display cells 10.When the place in dark makes light-emitting component 23 luminous, the light that comes self-emission device 23 direction guiding surfacewise in light guide plate 24.This light that is guided is hardly from the reflecting surface 30a reflection of each prism 130 of light guide plate 24, thereby directly is guided in light guide plate 24 along surface direction.
Because the prism 130 of light guide plate 24 is arranged to be roughly parallel to and is connected light-emitting component 23 and in the face of the line of a part of side surface of the light guide plate 24 of light-emitting component 23, the line that promptly connects 12 o'clock and 6 o'clock, the light of guiding from the reflecting surface reflection of prism 130, directly is guided in light guide plate 24 hardly in light guide plate 24.When this light that is guided arrived the side surface of light guide plate, shown in Figure 46 and 48, light also imported light guide plate 24 once more from side surface reflecting part 131 reflections on the side surface that is positioned at light guide plate 24.Because side surface reflecting part 131 forms roughly half-circle-arc shape on the side surface of light guide plate 24, wherein light guide plate 24 is for roughly discoid, the light of side that therefore arrives light guide plate 24 from side surface reflecting part 131 as the internal reflection of the light beam of almost parallel to light guide plate 24.
When the light of 131 reflections from the side surface reflecting part was guided light guide plate 24, light reflected to the lower face side of light guide plate 24 from the reflecting surface 30a of each prism 130 of light guide plate 24.Like this, carry out surface emitting from whole light guide plate 24, and the lower face side of the light directive light guide plate 24 of this surface emitting.Correspondingly, can be on the whole roughly illuminate the liquid crystal display cells 10 of the opening portion of the dial plate 13 that is positioned at light guide plate 24 downsides and corresponding dial plate 13 equably by this irradiates light.Therefore, even in the place of dark, also can pass through dial plate 13 and pointer 15 recognition times, and can discern the information that is presented on the liquid crystal display cells 10.
Since from light-emitting component 23 enter light guide plate 24 and the light of guiding light guide plate 24 not from prism 130 reflection of light guide plate 24 but surfacewise direction directly guide, therefore do not produce bright line spectrum 33 as shown in figure 49.Promptly, as the 9th embodiment shown in Figure 39, if the prism 125 on the upper surface of light guide plate 24 is arranged to be approximately perpendicular to and is connected light-emitting component 23 and in the face of the line of a part of side surface of the light guide plate of light-emitting component 23, the line that promptly connects 12 o'clock and 6 o'clock, and the reflecting surface 25a of prism 125 be arranged in the face of light-emitting component 23 sides or 12 o'clock side, when the light that comes self-emission device 23 entered light guide plate 24 and guide in light guide plate 24, light reflected to the lower face side of light guide plate 24 from the reflecting surface 25a of each prism 125.Therefore, as shown in figure 49, when when the light traffic direction is watched catoptrical part, these parts form the dot-and-dash line shape, and regard bright line spectrum 33 as.Yet, as the tenth embodiment, when enter light guide plate 24 from light-emitting component 23 and the light of guiding light guide plate 24 not from the reflecting surface 30a reflection of the prism 130 of light guide plate 24 but, therefore do not produce bright line spectrum 33 directly along the surface direction guiding.
Correspondingly, in this wrist-watch, when the place in dark made light-emitting component 23 luminous, light entered light guide plate 24 and guides along surface direction light guide plate 24 from side surface.The light of this guiding is from the reflecting surface 30a reflection of the prism 130 of light guide plate 24 but direct direction guiding surfacewise hardly.When this light arrived the side of light guide plate 24, light was from the internal reflection of side surface reflecting part 131 to light guide plate 24.Because this reflected light reflects to the lower face side of light guide plate 24 from the reflecting surface 30a of each prism 130, therefore carries out surface emitting from whole light guide plate 24, thereby roughly illuminates dial plate 13 and the liquid crystal display cells 10 that is positioned under it on the whole equably.In this case owing to do not produce as shown in figure 49 dot-dash wire bright line spectrum 33, therefore can be under the situation that not influenced by bright line spectrum 33 by dial plate 13 and liquid crystal display cells 10 identifying information and time well.
In the tenth embodiment, prism 130 is formed on the upper surface of light guide plate 24, thereby makes reflecting surface 30a point to 9 o'clock side, and side surface reflecting part 131 be arranged on from 12 o'clock on the part on the side surface of the light guide plate 24 at 6 o'clock to 9 o'clock.Yet be not limited thereto.For example, retrofit as second shown in Figure 50 and 51, prism 34 can be formed on the upper surface of light guide plate 24, make reflecting surface 34a point to 3 o'clock side (right side among Figure 51), and side surface reflecting part 135 can be arranged on from 12 o'clock on the part on the side surface of the light guide plate 24 at 3 o'clock to 6 o'clock.In this case, the spacing of preferred prism 34 with its away from side surface reflecting part 135 sides or 3 o'clock side and narrowing down gradually.
In this structure of second remodeling, when the light that comes self-emission device 23 enters light guide plate 24 and when surface direction is guided, and thereby this guide lights arrives side surface 135 reflections from the side surface reflecting part of light guide plate 24, and this reflected light guide in light guide plate 24 and reflected to the lower face side of light guide plate 24 from the reflecting surface 34a of prism 34.Thus, shown in the tenth embodiment, do not produce bright line spectrum 33, and can illuminate dial plate 13 and liquid crystal display cells 10 equably on the whole.
