The invention provides a pixel structure, a transparent touch display screen and a manufacturing method thereof, and a display device. The transparent touch display screen includes a plurality of rows and columns of pixel structures arranged in an array, and each pixel structure includes a display region provided with an organic electroluminescent device and a transparent region provided side by side with the display region. A first and a second touch capacitor electrodes made of a transparent conductive material are respectively provided in every two adjacent transparent regions in the same row, every two adjacent first touch capacitor electrodes in the same row are electrically connected with each other by a first connection line extending in the row direction, every two adjacent second touch capacitor electrodes in the same column are electrically connected with each other by a second connection line passing through the display region in the column direction.
