Problems solved by technology

However, this approach will lead to the inability to properly squeeze the upper and lower substrates due to the rigidity of the gap support during the assembly process of the panel, thereby reducing the pass rate of the one drop fill (ODF) process of liquid crystals. And cause the phenomenon of liquid crystal vertical flow or bubbles

Embodiment Construction

[0049] FIG. 2 is a schematic cross-sectional view of a liquid crystal display panel in a preferred embodiment of the present invention. Referring to FIG. 2 , the liquid crystal display panel 200 is mainly composed of a first substrate 210 , a second substrate 220 , a liquid crystal layer 230 and a spacer 240 . Wherein, the second substrate 220 is disposed above the first substrate 210 . In this embodiment, the first substrate 210 is, for example, an active device array substrate composed of a transparent substrate 212 and a plurality of active devices 214 and pixel electrodes 216 disposed thereon. Moreover, since thin film transistors (thin film transistors, TFTs) have good response speeds, in this embodiment, for example, thin film transistors are used as the active elements 214 for driving the liquid crystal display panel 200 . In other words, the first substrate 210 of this embodiment is preferably a thin film transistor array substrate.

Abstract

The LCD panel comprises: a first substrate with a second one on top, a LC layer and some gap support material both arranged between substrates. Wherein the support material includes multiple support structures every with two parts, the near first parts connect with each other, while the second part separates away. This invention can improve panel assembly up-to-standard rate.

Description

technical field [0001] The invention relates to a display panel, and in particular to a liquid crystal display panel with good assembly yield. Background technique [0002] The rapid progress of the multimedia society is largely due to the rapid progress of semiconductor devices and display devices. As far as displays are concerned, liquid crystal displays (Liquid Crystal Displays, LCDs) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0003] FIG. 1 is a schematic cross-sectional view of a conventional liquid crystal display panel. Referring to FIG. 1 , the liquid crystal display panel 100 is composed of a lower substrate 110 , a liquid crystal layer 120 and an upper substrate 130 . Wherein, the liquid crystal layer 120 is sealed between the lower substrate 110 and the upper substrate 130 by a sealant (not shown in the figure). In addit...
