Provided are an array substrate (01), a
liquid crystal display screen, and a
display device. The
liquid crystal display screen comprises the array substrate (01), an opposite-direction substrate (02) opposite to the array substrate (01), and a
liquid crystal layer (03) provided between the array substrate (01) and the opposite-direction substrate (02), the array substrate (01) having multiple
metal signal lines (011) provided within an effective display area thereof. The
liquid crystal display screen further comprises
first light shielding portions (041), the
first light shielding portions (041) corresponding to the
metal signal lines (011) in a one-to-one relationship, and each being located at one side, facing away from the liquid
crystal layer (03), of the corresponding
metal signal line (011), and an
orthographic projection of each
first light shielding portion (041) on the array substrate (01) covering an
orthographic projection of the corresponding metal signal line (011) on the array substrate (01). Because the disposed first light shielding portion (041) can block the external light from irradiating the metal
signal lines (011) from the array substrate (01) side, the metal
signal lines (011) are prevented from reflecting the light, thereby improving a viewing effect of a
transparent display from the array substrate (01) side and achieving double-side display.
