In bright preferred embodiment, reduce TFT single-glasses 17 and the wiring on the 15 corresponding region of the first perforate on shading glue film 14
Density so that TFT single-glasses 17 are with the wiring density on the 15 corresponding region of the first perforate on shading glue film 14 less than pre-
If density threshold, or TFT single-glasses 17 are turned with the wiring on the 15 corresponding region of the first perforate on shading glue film 14
Move on to other positions so that TFT single-glasses 17 with the 15 corresponding region of the first perforate on shading glue film 14 without wiring, because
This, can be irradiated on button 13 through TFT single-glasses 17 to greatest extent by the light after the first perforate 15.
It is noted that for protect TFT single-glasses light-sensitive emulsion (U ltravio l et Rays, hereinafter referred to as
UV glue) positioned at TFT single-glasses towards on the face of touch layer, UV glue be transparent configuration, the inside of light-transmissive UV glue.
In the above-described embodiments, in backlight 11 16 the first perforate of distance 15 of light source and button 13 is relatively near, light source 16
A part of light in the light for going out can directly pass through the first perforate 15, so as to be radiated on button 13；In the present embodiment, backlight
16 the first perforate of distance 15 of light source and button 13 in source 11 farther out, in such a case, it is possible to the glue frame in backlight 11
The guide-lighting groove 24 that a part of light that light source 16 sends can be guided in the first perforate 15 is set on 23, Fig. 9 and Figure 10 is referred to,
13 corresponding position of button is played from the position of light source 16 in glue frame 23 and opens up guide-lighting groove 24, what the light source 16 of backlight 11 sent
Light Jing has the inwall reflection of the glue frame 23 at certain angle of inclination, is irradiated to the button 13 of touch layer 12 by the first perforate 15
On, or the gap between the edge by TFT single-glasses 17 and glue frame 23 is irradiated on the button 13 of touch layer 12, is realized
Illuminate the purpose of button 13.It is noted that the reflectance of 23 pairs of light of glue frame is up to 97%, therefore, glue frame 23 can be efficient
A part of light that light source 16 is sent reflex between the first perforate 15 or the edge and glue frame 23 of TFT single-glasses 17 between
In gap.
