Problems solved by technology

However, because the size of the polarizer 12 is insufficient, the frame glue 16 will straddle the side surface 120 of the polarizer 12 during the coating process, and cannot be completely coated on the polarizer 12, and the strength of the frame glue 16 is insufficient to be effective. The force of blocking the outward flow of the colloid 15 will cause the colloid 15 to overflow the glue, which will eventually lead to the failure of bonding the covering substrate 14, and may even cause the colloid 15 to flow into the liquid crystal display device and cause damage

Embodiment Construction

[0053] Please refer to figure 2 , figure 2 It is a schematic cross-sectional view of a display panel according to an embodiment of the invention. The display panel 2 is, for example, a liquid crystal display panel or a self-luminous display panel. Such as figure 2 As shown, the display panel 2 in this embodiment includes a first substrate 20, a second substrate 21, a polarizer 22, and a sealant 23. The first substrate 20 is disposed relative to the second substrate 21. The first substrate 20 is, for example, a thin film transistor array substrate, and the second substrate 21 is, for example, a color filter substrate, but the invention is not limited to this. The polarizer 22 has a plurality of holes 220, and the second substrate 21 is located between the first substrate 20 and the polarizer 22. The sealant 23 is disposed on the polarizer 22. The sealant 23 has a plurality of protrusions 230 corresponding to the holes 220 of the polarizer 22, and the protrusions 230 are resp...

Abstract

A display panel comprises a first substrate, a second substrate, a Polaroid and a glue frame. The first substrate is opposite to the second substrate which is between the first substrate and the Polaroid. The Polaroid is provided with a plurality of holes and the glue frame is disposed on the Polaroid. The glue frame is provided with a plurality of projections corresponding to the holes and disposed in the holes respectively. According to the invention, the stability of the glue frame on the Polaroid is improved in a cover substrate fit process because the projections of the glue frame are disposed in the holes of the Polaroid and the glue frame will not collapse because of press during fit of cover substrates. The adhesiveness of the glue frame is increased, so that glue between the cover substrates and the Polaroid can be limited in the glue frame effectively and glue overflow is prevented.

Description

Technical field [0001] The present invention relates to a display panel, and more particularly to a display panel with a structure for enhancing the adhesion of sealant. Background technique [0002] With the advent of the digital age, the technology of display devices has also grown rapidly and has become an indispensable electronic product. Therefore, the technical and functional requirements for display devices have become higher and higher. Among them, liquid crystal display devices are popular among high-end products because of their high brightness and large viewing angle. [0003] The liquid crystal display device mainly includes a liquid crystal display panel and a backlight module. The main structure of the liquid crystal display panel is as figure 1 As shown, the liquid crystal display panel 1 includes a color filter substrate 10, a thin film transistor array substrate 11, polarizers 12, 13, a cover substrate 14, and the like. Such as figure 1 As shown, the color filter...
