New description: [New technical field] The present invention relates to a button device having a light-emitting structure, in particular to a surface light source device having high uniformity. [Prior Art] According to the current mobile phone keypad device, the light-emitting diode (LED) light source of the TQpView is used instead of the flat light source. It is also difficult to use the button device of the ultra-thin mobile phone because it is easy to cause the brightness uniformity to be poor and the problem of poor heat dissipation to occur. In addition, as in the Republic of China Patent Bulletin No. 2, 414, 1 「 "Pocket keyboard with electric excitation light rubber button and its manufacturing method", it is a stone eve corresponding to the illuminating part of the front side of the __ Shen Wei illuminating element On the layer, the objective of the planar light source is achieved by using the electroluminescent element as the f-light source. However, such an electroluminescent device is used as a planar illumination device keyboard device, and it is necessary to operate the electroluminescence device together with the driver 1C to operate. Thus, there is a problem of electrostatic discharge protection (Eieetr. ESD). The stability of the product is not good. In view of the above problems, this creation overcomes the problem of the light source of the conventional button device (4) and provides a button device design that is simple in structure and can reduce the manufacturing cost.
