摘要： Disclosed are a display panel, a method for manufacturing the same and a display device, which relate to the field of display technologies. A second cathode layer included in the display panel is provided with a hollowed-out region, such that the second cathode layer will not entirely cover a second display region. Compared with a cathode layer that entirely covers the second display region, the second cathode layer can effectively reduce the impact on the light transmittance. Thus, a camera disposed in the second display region has an excellent imaging effect.
