Description

Display panel

The present invention relates to a display panel, and more particularly to a display panel provided with a continuous spacing structure.

The current display panel is composed of two substrate structures and a display medium layer disposed between the two substrate structures. Taking a liquid crystal display panel as an example, it includes an array substrate structure, a pair of substrate structures, and a liquid crystal layer disposed therein. Generally, a spacer is disposed between the array substrate structure and the opposite substrate structure to maintain a fixed cell gap between the array substrate structure and the opposite substrate structure.

Before the liquid crystal display panel is shipped from the factory, a press test must be performed to ensure that the spacer can effectively support the liquid crystal gap fixed by the array substrate structure and the opposite substrate structure. However, it has been found through empirical results that after a conventional down-liquid test (for example, 100,000 times), the conventional force of the liquid crystal display panel causes the spacer to be damaged and the liquid crystal gap is mutated, which seriously affects the display uniformity.

One of the objects of the present invention is to provide a display panel having high display uniformity and reliability.

An embodiment of the present invention provides a display panel having an active area and a peripheral area, and the peripheral area surrounds the active area. The display panel includes a first substrate structure and a second substrate A structure, at least a first continuous spacer structure, and a display dielectric layer. The second substrate structure is disposed opposite to the first substrate structure. The first continuous spacer structure is disposed between the first substrate structure and the second substrate structure and located in the active region, wherein the first continuous spacer structure comprises a first buffer base and a plurality of first spacers, and the first buffer base is A continuous film layer is disposed on the first substrate structure, the first spacer is in contact with a surface of the first buffer base, and the first buffer base is integrally formed with the first spacer. The display medium layer is disposed between the first substrate structure and the second substrate structure.

The display panel of the present invention has a continuous spacing structure including an integrally formed buffer base and a plurality of spacers, which can be empirically reduced to greatly reduce the pressing force of a single spacer when pressed by an external force, thereby preventing the spacer from being repeatedly applied. Damage to the press allows the display panel to maintain a fixed gap, ensuring display uniformity and reliability.

The height is such that the main spacer 161M is in contact with the second substrate structure 20, and the sub spacer 161S is not in contact with the second substrate structure 20. Precisely, when not pressed by the external force, the main spacer 161M is in contact with the second substrate structure 20 to maintain the liquid crystal gap, and the sub spacer 161S is not in contact with the second substrate structure 20.
