- the temperature of the sealant is thermally controlled to be between 100 ° C and 180 ° C. This is because when the temperature is too low, the reaction temperature at which the thermochromic material is discolored cannot be reached, and the temperature is high. Although the reaction speed can be accelerated, the temperature is too high and the surface of the sealant is easily uneven. Further, for example, heat the sealant The temperature at the time of curing treatment is controlled at about 130 °C.
- the sealant is heated.
- the colorless 2-phenylamino-3-methyl-6-diethylaminofluoran and boric acid in the sealant are discolored into a black material after heat curing, thereby making the sealant black It can effectively prevent light leakage from the display panel.
- the array substrate faces the opposite substrate side and the opposite substrate faces the array substrate.
- a flattening layer is provided on each side. For example, no flattening layer is provided in the frame area to ensure that the ultraviolet light can be sufficiently irradiated on the sealant.
- the front projection of the peripheral circuit and the wire pattern in the frame region on the array substrate does not overlap with the orthographic projection of the black matrix pattern on the array substrate. That is, no black matrix is set in the area where the peripheral circuit and the wire pattern are located.
- the ultraviolet light may not be irradiated from the side of the array substrate for the area where the peripheral circuit and the wire pattern are located, so that the gap width in the pattern of the peripheral circuit and the wire can be reduced.
- the sealant contains a substance formed by the discoloration of the thermochromic material during the curing process, the display panel does not have a black matrix in the region where the peripheral circuit and the wire pattern are located, but the curing process is performed.
- the rear sealant itself can prevent the display panel from leaking light.
