Abstract

The invention provides a touch display device which comprises a display panel and a touch panel. The display panel is provided with a display surface, and the touch panel is arranged on a display surface side. The touch panel comprises a first membrane, a second membrane and a plurality of sensing electrodes, wherein the sensing electrodes are arranged on at least one of the first membrane and the second membrane. The first membrane and the second membrane are made of double-refraction materials and respectively provided with a fast-axis axial direction, and the fast-axis axial direction angle difference of the first membrane and the second membrane ranges from 70 degrees to 110 degrees. The invention further provides a manufacturing method of the touch display device.

Description

Technical field [0001] The invention relates to a display device and a manufacturing method thereof, in particular to a touch display device and a manufacturing method thereof. Background technique [0002] All kinds of touch display devices have become indispensable daily necessities in the lives of modern people. In response to the fierce competition in the market and the increasing demands of consumers, the display quality of touch display devices has also become the design of the industry One of the important considerations. [0003] In the known technology, the touch panel body has an upper and a lower PET film, which are respectively manufactured by a roll-to-roll method. However, the PET film made by rolling and stretching is optically anisotropic, which will affect the travel speed of light. Therefore, whether the incident light or the light from the liquid crystal display panel passes through the PET film, the problem of phase retardation will occur, and the light will h...
