Abstract: A display panel with enhanced waterproof ability is disclosed and includes a thin film transistor glass substrate, a color filter glass substrate, a frame sealing layer, and a liquid crystal layer. The color filter glass substrate is opposite to the thin film transistor glass substrate. The frame sealing layer and liquid crystal layer are disposed between the thin film transistor glass substrate and the color filter glass substrate. A planarization layer and a passivation layer are sequentially stacked on a surface of the thin film transistor glass substrate facing the frame sealing layer. An outer periphery of the planarization layer adjacent to the narrow bezel display panel is defined with a waterproof groove. The passivation layer extends to a portion adjacent to the waterproof groove without extending into the waterproof groove. Outer peripheries of the passivation layer and the display panel are at an interval to improve waterproof ability.
