A stereoscopic image display device capable of reducing grid visual effect includes a flat display unit, a light source unit disposed on a side of the flat display unit, and a lens array unit disposed on another side of the flat display unit. A light source provided by the light source unit satisfies an optical characteristic as follows: an attenuation amplitude of a luminance of the light source before entering the lens array unit being not greater than 65% within a divergence angle of a light field system of the stereoscopic image display device, thereby reducing the grid visual effect of a stereo image generated by the stereoscopic image display device.

An array substrate and a display panel. The array substrate includes: a base layer including at least one base sub-layer each being a light-transmitting layer; a transistor layer on the base layer, the transistor layer including a plurality of transistors; and at least one light adjustment layer on a side of the transistor layer facing the base layer, the at least one light adjustment layer being configured to block, at least in a preset state, light from at least one side of the at least one light adjustment layer. In the array substrate, the amount of light irradiated on the transistor layer from the side of the base layer is reduced and the photo-induced leakage current in the transistors in the transistor layer is reduced, thus alleviating locally non-uniform brightness of a displayed image.
