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 present 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 are indispensable daily necessities in the life of modern people, and in response to the fierce competition in the market and the continuous improvement of consumer requirements, the display quality of touch display devices has also become a design choice for the industry. one of the important considerations. [0003] In the known technology, the touch panel body has two upper and lower PET films, which are respectively made by roll-to-roll. However, the PET film produced by roll stretching is optically anisotropic, which will affect the speed of light travel. Therefore, no matter the incident light or the light from the liquid crystal display panel passes through the PET film, there will be a problem of phase delay, and then t...
