  • Patent number: 9857650
    Abstract: The present invention teaches an array substrate and a liquid crystal (LCD) panel including the array substrate. The array substrate contains a substrate, a number of scan lines, a number of data lines, and a number of common scan lines. The scan lines and the common scan lines are alternately interleaved with the data lines on the substrate so as to form a number of pixel units. Each pixel unit contains a main pixel unit and a sub pixel unit. The sub pixel units from two neighboring pixel units share a common scan line which drives the two sub pixel units simultaneously. As such, the number of common scan lines is reduced, thereby enhancing pixel aperture ratio.

  • Patent number: 9726938
    Abstract: Red pixels (R), blue pixels (B) and green pixels (G) are formed in parallel. First columnar spacers 10 and second columnar spacers 20 are formed on a first substrate. The distance between the first substrate and a second substrate in a normal state is determined by the first columnar spacers 10. The diameter of a light blocking film corresponding to each first columnar spacer 10 is greater than the diameter of a light blocking film corresponding to each second columnar spacer 20. The first columnar spacer 10 is not formed at a boundary between a green pixel (G) and a red pixel (R) or a boundary between a green pixel (G) and a blue pixel (B). The second columnar spacer 20 is formed at a boundary between pixels irrespective of the pixel color. Thus, appropriate color balance can be attained with ease without having a drop in the luminance.

  • Patent number: 9703147
    Abstract: A liquid crystal display device filled with a liquid crystal according to one drop filling prevents the liquid crystal from penetrating between a sealant and a TFT substrate or a counter substrate so as to reduce bonding strength in a seal part. The seal part has a wall spacer around the periphery of the sealant. In a terminal-side seal part, a second sealant is formed outside the wall spacer while a second wall spacer is formed outside the second sealant. Thus, the sealant, the wall spacer, and the sealant are sequentially formed in a plan view of a motherboard including liquid crystal display panels to be separated. This configuration can prevent the liquid crystal from penetrating into the seal part according to an internal pressure.
