Description

technical field [0001] The invention relates to a touch screen and a manufacturing method thereof. Background technique [0002] With people's demands for diversification, it is more and more popular to use a touch screen instead of a keyboard or a mouse to control a liquid crystal display device. Currently, the more commonly used touch screens are resistive touch screens and capacitive touch screens. [0003] Among them, the structure of the resistive touch screen is as follows: figure 1 As shown, it includes an upper substrate 015 , a lower substrate 011 , an upper conductive layer 014 , and a lower conductive layer 012 , and a spacer 016 is provided between the upper and lower conductive layers to form a cavity 013 . Due to the existence of the cavity 013, the resistive touch screen is relatively thick and the cavity will seriously hinder the transmission of light, resulting in a low transmittance of the resistive touch screen. Likewise, there are similar deficiencies ...
