Embodiment Construction

[0054] As used herein, "about," "approximately," "essentially," or "essentially" includes the stated value and the average within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art, taking into account the The measurement in question and the specific amount of error associated with the measurement (ie, limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or for example within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, "about", "approximately", "essentially" or "substantially" used herein may select a more acceptable range of deviation or standard deviation according to measurement properties, cutting properties or other properties, and may not use One standard deviation applies to all properties.

[0055] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. It will be understood that when an elem...

Abstract

A display device includes a substrate, a first element layer, a second element layer, a first adhesive layer and a display element layer. The first element layer, the first adhesive layer, the second element layer and the display element layer are sequentially stacked on the substrate. The first element layer includes a plurality of signal lines and a first thin film transistor. The first thin film transistor has a first gate, a first source, a first drain and a first semiconductor pattern. The second element layer includes a second thin film transistor electrically connected to the first thin film transistor. The second thin film transistor has a first polysilicon semiconductor pattern. At least one of the first gate, the first source and the first drain belongs to the same film layer as the plurality of signal lines. The material of the first semiconductor pattern includes metal oxide semiconductor or amorphous silicon semiconductor.

Description

technical field [0001] The present invention relates to a display device, and in particular to a high-resolution display device. Background technique [0002] With the development of the technology industry, display devices such as mobile phones, tablet computers or eBooks have been widely used in daily life. Especially in recent years, with the emergence of multimedia applications such as stereoscopic display and virtual reality, in order to provide stunning visual effects, the demand for display panels with ultra-high resolution has gradually increased. [0003] As the resolution of the display panel continues to increase, it is one of the current solutions to design the driving circuit under the pixel structure in a stacked structure to solve the shortage of layout space for the driving circuit. However, using the stacked structure will inevitably increase the complexity of the manufacturing process and the production cost. Therefore, how to simplify the manufacturing p...
