Abstract

The present invention provides a display device and a preparation method thereof. Black matrices are arranged at outside of a light outlet side of the display device, and the black matrices are bakedwhen the black matrices are prepared, causing the problem of insufficient water vapor release in the black matrices. Because the black matrices are not arranged between two corresponding substrates, correspondingly, the black matrices can not affect liquid crystal molecules in the display device, the additional baking process is not needed, and thus both of the capacity of the display device and the display effect are ensured.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a display device and a preparation method thereof. Background technique

[0002] Whether it is a conventional liquid crystal display panel or a COA (Color Filter On Array) liquid crystal display panel, the sub-pixels are blocked by a black matrix. If the black matrix is ​​not fully released during the preparation process, there are bubbles in it, and the gas will enter the liquid crystal layer. Inside, it affects the birefringence of liquid crystal molecules, thus affecting the display effect. In conventional liquid crystal display panels, R, G, B color resistance and black matrix are all made on the color filter substrate, and the black matrix is ​​prepared first, and then the R, G, B color resistance is prepared, because the R, G, B color resistance Both the black matrix process and the black matrix process have a baking link. For the black matrix, not only the baking is perf...

Embodiment Construction

[0036] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] Such as figure 2 As shown, the present invention provides a display device, which includes: a first substrate 1, a black matrix 3 and a second substrate 2 that is boxed with the first substrate 1, and the black matrix 3 is arranged on the first substrate 1 away from the second substrate. One side of the second substrate 2, the side of the first substrate 1 where the black matrix 3 is located is the light emitting side of the display device.

[0038] The display device is a liquid ...
