Embodiment 1

[0027] figure 1 It is a schematic diagram of the structure of the peripheral region of the LCD panel provided by the first embodiment of the present invention. In this embodiment, a light-reflecting layer (hereinafter referred to as the first light-reflecting layer) is formed on a side of the peripheral area of ​​the CF substrate facing the sealant, that is, the first light-reflection layer and the sealant are located on the same side of the CF substrate. like figure 1 As shown, the liquid crystal display panel of this embodiment includes: a CF substrate and an array substrate, and the CF substrate and the array substrate are disposed opposite to each other up and down.

[0028] The array substrate mainly includes: a second transparent substrate 21 and an array structure pattern formed on the second transparent substrate 21 . The array structure pattern is the same as that of the prior art. For example, the array structure pattern (not shown) includes: a gate line pattern, a...

Embodiment 2

[0041] figure 2 It is a schematic diagram of the structure of the peripheral area of ​​the LCD panel provided by the second embodiment of the present invention. like figure 2 As shown, the difference between the LCD panel of this embodiment and the LCD panel of the first embodiment of the present invention is that the LCD panel of this embodiment is formed with a reflective layer (hereinafter referred to as the first Two reflective layers 42 ), that is, the second reflective layer 42 and the sealant 3 are located on two opposite sides of the array substrate. Specifically, the second reflective layer 42 and the array pattern are respectively formed on two opposite surfaces of the second transparent substrate 21, the second reflective layer 42 is formed on the side of the second transparent substrate 21 close to the backlight source, and at least partially covers the The array substrate is used for coating or aligning the corresponding area of ​​the sealant 3 to reflect the ...

Embodiment 3

[0055] image 3 It is a flow chart of the manufacturing method of the LCD panel provided by the third embodiment of the present invention. like image 3 As shown, the manufacturing method of the LCD panel of the present embodiment includes:

[0056] Step 31: Prepare the first substrate (such as CF substrate) and the second substrate (such as array substrate) by patterning process, the peripheral area of ​​the first substrate or the peripheral area of ​​the second substrate is formed with a reflective layer.

[0057] For TFT-LCD, the two substrates that make up the LCD panel are: CF substrate and array substrate. It may be advisable to use the CF substrate as the first substrate in this embodiment, and use the array substrate as the second substrate in this embodiment.

[0058] If a reflective layer (that is, the first reflective layer) is formed on the peripheral area of ​​the CF substrate, the first reflective layer is formed on the side of the peripheral area of ​​the CF ...

Abstract

The present invention relates to a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises a first substrate and a second substrate that are assembled opposite to each other; liquid crystal is filled between the display area of the said first substrate and the display area of the said second substrate; sealing glue is formed between the peripheral area of the said first substrate and the peripheral area of the said second substrate; a reflection layer is formed on the peripheral area of the said first substrate or the peripheral area of the said second substrate. The said reflection layer is used to reflect the incident ultraviolet light to the said sealing glue in the process of assembling the said first substrate and the said second substrate. The liquid crystal display panel and the manufacturing method thereof provided in the present invention increase the utilization rate of ultraviolet light in the process of solidifying the sealing glue when assembling the two substrates by arranging reflection layers on the peripheral area of one of the two substrates that constitute the liquid crystal display panel, and helps to lower the probability of defects occurring to the LCD panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] A liquid crystal display panel for a Thin Film Transistor Liquid Crystal Display (TFT-LCD) mainly includes a color filter (Color Filter, CF) substrate and an array (Array) substrate, as well as a CF substrate and an array substrate. Liquid crystal layer filled between the substrates. The process of setting the pre-prepared CF substrate and the array substrate in the box is called the "box-to-box process". The peripheral area of ​​the other substrate is uniformly coated with sealant; after the coating of the sealant and the liquid crystal dripping are completed, the two substrates are accurately boxed, and the sealant is cured to achieve the lamination of the two substrates . The substrate coated with sealant can be a CF substrate, and the substrate dripped with liquid crystal can ...
