The invention relates to a μLED light-emitting and display device with single-ended electrical contact and single-ended carrier injection, and a manufacturing method of the μLED light-emitting and display device. The μLED light-emitting and display device comprises more than one pixel unit, and each pixel unit sequentially comprises a lower pixel electrode, μLED chips, an insulating layer, and an upper pixel electrode from bottom to top, wherein the μLED chips directly contact with the lower pixel electrode, external carriers are injected into the μLED chips through the lower pixel electrode, the insulating layer prevents the external carriers from being injected into the μLED chips through the upper pixel electrode, and the μLED chips are lit by an alternating electric field applied between the upper pixel electrode and the lower pixel electrode. The invention avoids the complicated bonding process, and is expected to improve the market competitiveness of the μLED light-emitting and display device.
