ABSTRACT:
A display panel includes lower and upper glass substrates. The lower glass substrate includes a pixel array having a plurality of pixel units formed thereon, wherein each pixel unit includes a transparent domain and an opaque domain surrounding the transparent domain, and an upward projection is formed in the opaque domain on the lower glass substrate. The upper glass substrate, mounted on the lower glass substrate, has a spacer formed therebeneath and protruded downwarly therefrom for keeping a cell gap between the upper and lower glass substrates, wherein the spacer is fallen in the opaque domain and has a lateral side in collision with the projection on the lower glass substrate to prevent relative displacement between the lower and upper glass substrates.
