Description of the Invention: [Technical Field] The present invention relates to a touch display device and a method of fabricating the same, and more particularly to a touch device having a simplified manufacturing process and improving the optical effect of the panel Display device and method of manufacturing the same. [Prior Art] The touch panel has been widely used in a variety of electronic instruments, including some that can be carried around, emphasizing light and short electronic instruments: such as personal digital assistants (PDAs), electronic dictionaries, watches, computers or notes. Computer, etc. It is quite convenient to use the touch panel, and no additional input device such as a keyboard is added, which greatly reduces the weight of the device. In terms of market demand today, the lighter and more convenient to carry, the more competitive the market. The touch panel can be classified into a resistive touch panel, a capacitive touch panel, an optical touch panel, and an electromagnetic touch panel according to different configurations and sensing forms. The touch panel design used in general flat display devices, such as the resistive touch panel, is composed of two layers of indium tin oxide (ITO) polyester film (PET film) layer and glass layer. , the middle sprinkle support particles (Spacer) to achieve. A conventional flat display device, please refer to Fig. 1, which is a schematic cross-sectional view of a front light reflective display device. The light-reflective display device comprises a display panel 15A, and a front light plate 130 is disposed on the upper surface of the front light plate 13 and a light source 11 is disposed on the side of the touch panel module 120', and the front light plate 13 is disposed. , display 201115210 panel 150 and money i1G system capacity - shell (10) ~. The touch panel module 12G includes a transparent glass layer 125. The upper surface of the glass layer 125 is plated with an indium tin oxide layer 124, which is a (four) f° (four) oxide layer 124.

When the touch panel is used, 'if the polyester film ^ 121 is subjected to pressure at a certain point, this causes - The indium tin oxide layer 122 of the indium tin oxide layer 124 contacts the current path to generate an electronic signal for inputting the signal. The touch module 12 is also provided by a spacer structure 14 Attached to the front light plate m or the housing i (9). Further, after the light source m is guided by the front light plate 130 to the display panel 15 , the front light plate 130 , the glass layer 125 , and the indium tin oxide layer 124 are required to be penetrated. The indium tin oxide layer 122 and the polyimide (four) layer 121 can penetrate to the outside due to the penetrating layer The result is that the brightness is insufficient or the color is dark, and the display effect is not good. Because of the design of the touch panel in the past, the touch module and the display module are all independently designed, 'the number of layers is quite large, and the process is complicated. , 'the thickness is not easy to fall, and the optical effect of the light transmission efficiency or the color display is also reduced.

In order to make the first transparent substrate 21 have a light guiding effect, the first transparent substrate 21 is provided with a light guiding structure 211 on a surface, which is groove-shaped, which can be laser engraved, printed, etched, and cut. Formed by injection molding or attaching a layer of microstructured film. Here, the hardness of the first transparent substrate 21 is reinforced to prevent scratching, and the first transparent substrate 21 may be provided with a transparent hardened layer 212 on one side thereof in a coating manner as needed. The first conductive layer 22 may be made of indium tin oxide (IT〇), which may ride on the first transparent substrate 21 in a physical vapor deposition (PVD) manner and on the surface of the light guiding structure 211. In addition, after the first transparent substrate 21 is provided with the first conductive layer 22, an etch process is performed on the first conductive layer, and a plurality of conductive lines are disposed to coat the silver paste for transmitting electrical signals. 201115210 The first transparent substrate 25 can be made of acrylic (PMMA), PET film, glass or polycarbonate (pc).
