Display panels and display devices

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes: a first substrate; connected to the second substrate opposite to each other through a frame glue; display medium molecules are arranged in the accommodation space formed by the first substrate, the second substrate, and the frame glue; and spacers, It is arranged in the accommodation space and includes a first spacer unit and a second spacer unit, the first substrate includes a first part and a second part with different heights, one end of the first spacer unit is connected to the first part, and the first spacer unit The other end is against the second substrate, the second spacing unit is a sheet structure and includes a main support column and a sub-support column connected to the main support column, one side of the main support column and the sub-support column is connected to the second part, and the main support column The other side of the pillar and the sub-support pillar has a predetermined interval from the second substrate. Therefore, the embodiment of the present invention can increase the step difference between the first and second spacer units.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Multi-Chip Process (MCP, Multi-Chip Process) is often used in the manufacture of display panels. It can cut several smaller display panels suitable for different models on a large display panel. This technology can greatly Improve production efficiency and increase the utilization rate of glass substrates, thereby reducing production costs. The size of the cut display panel is usually not consistent, and when typesetting, the arrangement direction of the color resistance between the display panels suitable for different models is perpendicular to each other, and the display panels suitable for different models cut from the same display panel will appear LC Margin (the amount of liquid crystal corresponding to the thickness of the cell has an upper and lower limit, and the middle value of the upper and l...

Problems solved by technology

[0004] According to the design requirements of the liquid crystal display panel, the main compartment unit and the auxiliary compartment unit are arranged in the display area (AA area) of the liquid crystal display panel in an orderly manner with a certain arrangement rule and distribution density. However, the existing main compartment unit and auxiliary compartment unit The arrangement rules of columnar spacers such as spacer units cannot improve the level difference between the main spacer unit and the auxiliary spacer unit

[0005] With the development of large-size and high-resolution LCD panels, the size of the pixels of the LCD panel is getting smaller and smaller. After the cell-forming process is completed, the semiconductor layer of the switching element such as the thin film transistor and the columnar spacer are sequentially arranged along the first direction. Arranged side by side, if the process is shifted along the first direction, there is a risk that the columnar spacer will stand outside the sub-pixel, which will reduce the LCmargin and the rate of the main spacer unit or the auxiliary spacer unit rate (that is, the main spacer unit in the effective display area or the total area of ​​the auxiliary spacers divided by the area of ​​the active display area); if the process tries to shift along the second direction opposite to the first direction, this will cause the columnar spacers to be separated from the semiconductor layer on the TFT substrate side If it is too close, there is a risk that the columnar spacers will touch the semiconductor layer, resulting in a decrease in the performance of the LCD panel
