Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to a top emission type display device and a manufacturing method thereof. The top emission type display device includes a substrate having a TFT driving array, an insulation layer, a circuit layer, a flat layer and a pixel electrode layer, wherein the insulation layer is arranged on the substrate, the circuit layer is buried in the insulation layer, an upper surface of the circuit layer is basically level with an upper surface of the insulation layer, the flat layer is arranged above the insulation layer and the circuit layer, and the pixel electrode layer is arranged onthe flat layer. The top emission type display device is advantaged in that the circuit layer is buried in the insulation layer, the upper surface of the circuit layer is basically level with the uppersurface of the insulation layer, the flat layer is arranged above the insulation layer and the circuit layer, the planarization effect can be better achieved, the flatness of the pixel electrode layer is effectively improved, and thereby light emission uniformity of sub pixels is improved.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a top emission display device and a manufacturing method thereof. Background technique [0002] Organic electroluminescent diodes (OLEDs) have the advantages of self-illumination, fast response, wide viewing angle, high brightness, and thinness. Therefore, it has become the two main research directions of display devices at present. The use of solution processing methods to fabricate OLED and QLED displays is an important direction for the future development of display technology due to its advantages of low cost, high productivity, and easy realization of large sizes. Among them, printing technology is considered to be the most effective way to realize OLED and QLED low-cost and large-area full-color display. [0003] At present, because OLED display panels need to use more complex driving circuits for compensation, a large part of the TFT backplane is covered by the driving cir...
