Summary of the invention
But, the glass substrate of prior art is implemented in the printing process of printing, at glass substrate master meter
Must be provided with not implementing the offset area of printing on the marginal portion in face, this can restrict such as possesses touch screen merit
Degree of freedom in the outward appearance of the portable set of energy and/or design.About this problem, enter referring to Fig. 6
Row further instruction.Fig. 6 is to represent the glass as portable set cover glass of the prior art
Glass substrate is arranged on the state diagram of printing equipment, and Fig. 6 (a) is top view, and Fig. 6 (b) is side view.
In the prior art, implement on the glass substrate, in the operation of printing, as shown in Figure 6, to set regularly
Put and install as printing object on the position alignment fixture on printing equipment (such as, screen process press)
Glass substrate, by such as silk screen printing formed printing layer.Now, when forming multi-sheet printed layer, formed
Take out glass substrate from fixture after undermost first printing layer, be dried in drying oven.This is dried
In the case of thermo-cured ink, such as, it is exposed to the temperature environment of 60～100 DEG C, in the feelings of UV cured printing ink
Under condition, irradiate the UV (ultraviolet) of specific accumulated energy, be thus dried.Then, it is used for being formed
On the fixture of the second printing layer, glass substrate is installed again, is consequently formed the second printing layer, carries out the most equally
It is dried.Multi-sheet printed layer is formed by repeating above-mentioned process.
But, in the case of generally implementing printing on the cover glass of portable set, when installing,
In the following side of printing surface, i.e. at internally installed various electronic equipments or distribution, the LED of portable set
Light-emitting components such as (Light Emitting Diode) light source or for pasting the two of cover glass and housing
Face adhesive tape or resin material, for these parts hidden, it should implement print on the outer peripheral portion of cover glass

It is printed and sheens, there is problem bright compared with other region the most in appearance.Therefore, relatively
In the glass substrate of given size, in order to visually coordinate and guarantee the display picture of maximum, preferably make
Side-play amount diminishes as far as possible.
It addition, possess in the portable set of touch screen function, by by electrode (the such as ITO of touch screen
(Indium Tin Oxide) film is the nesa coating of representative) when being pasted onto glass substrate first type surface to manufacture,
If to guarantee the biggest effective touch under the restriction condition of the shell dimension of the portable set of regulation
Screen display picture, needs to arrange touch screen on the narrow zone of the marginal portion of glass substrate first type surface
Multiple distributions.Now, if there is the skew that can not implement printing in the marginal portion of glass substrate first type surface
Region, then by the component of this offset area can make configurable touch screen distribution region become further narrow and
Distribution design is made to become difficulty.It addition, upper electrode and the lower electrode being arranged on glass substrate are pasted onto
Time together, touch screen distribution is configured to inner side dislocation by the component of offset area, and therefore application work becomes
Obtain difficult.
Further, the light-emitting component of the LED light source etc. being arranged on the back lighting of liquid crystal panel or operated key
It is typically mounted near substrate periphery, but when there is side-play amount, the gloss of substrate outer peripheral portion is the brightest, because of
The most inharmonic problem can be there is in this.
