Provided are a light beam direction controlling element and a display device configured such that warpage due to the thermal contraction of a light absorbing material is minimized, and such that adhesion between transparent substrates is enhanced, thereby improving reliability without decreasing productivity. The light beam direction controlling element comprises light transmission regions composed of a light transmission material arrayed on a substrate, and light absorbing regions composed of a light absorbing material filled in the gaps between the light transmission regions, the light absorbing regions restricting the direction of the light beam passing through the substrate. The light absorbing regions extend on the substrate surface in a first direction and a second direction orthogonal to each other. The light absorbing regions extending in the first direction and the light absorbing regions extending in the second direction intersect each other to have an L-shaped or a T-shaped intersected portion, while having at least one structure that divides the light absorbing regions in the regions extending in the first direction or in the second direction excluding the intersected portion. |
