Problems solved by technology
When the color filter substrate and the array substrate are boxed, it is necessary to ensure that the distance between the color filter substrate and the array substrate is equal everywhere, that is, to ensure that the thickness of the box is consistent, because the top of the spacer in the display area is higher than the spacer in the peripheral area. On the plane where the top is located, the spacers in the peripheral area cannot contact the array substrate, and cannot play the supporting role of the spacers, resulting in the problem that the substrate substrate in the peripheral area has no spacer support for a long time and the thickness of the box is locally uneven.

The invention discloses a color film substrate and manufacturing method of the color film substrate and a display device. The color film substrate and manufacturing method of the color film substrate and the display device are used for achieving consistency of the heights of spacers in a display region and the heights of spacers in a peripheral region on the color film substrate, and achieving the purpose that the thicknesses of the display region and the peripheral region in the display device of the color film substrate are the same due to the fact that the tops of the spacers are in the same plane. The color film substrate comprises the display region, the peripheral region and an insulating layer, wherein the display region and the peripheral region are located on a underlayer substrate, the display region comprises a black matrix, a color resin layer, a medium protection layer and a plurality of spacers, and the spacers are located on the overlapping region of the black matrix and the color resin layer; the insulating layer is located on the peripheral region and is located between the medium protection layer and the underlayer substrate, and the thickness of the insulating layer under the spacers of the peripheral region is equal to the sum of the thicknesses of the black matrix and the color resin layer which are located under the spacers of the display region.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate, a manufacturing method thereof, and a display device. Background technique [0002] In the field of display technology, both thin film transistor liquid crystal display (Thin Film TransistorLiquid Crystal Display, TFT-LCD) and organic light emitting display (Organic Light Emitting Diode, OLED) include color filter substrate (CF substrate) and setting for light filtering Array substrate (Array substrate) with TFT pixel array. [0003] In order to ensure that the cell thickness between the color filter substrate and the array substrate after the cell alignment process is consistent, that is, to ensure that the vertical distance between the base substrate in the color filter substrate and the base substrate in the array substrate is equal everywhere, the color filter substrate Spacers of equal height are arranged between the array substrate ...
