Abstract
An electronic device may have a liquid crystal display with backlight structures. The backlight structures may produce backlight that passes through display layers in the display. The display layers may include color filter elements, a liquid crystal layer, and a thin-film transistor layer. The color filter elements may be interposed between the thin-film transistor layer and the backlight structures or the thin-film transistor layer may be interposed between the color filter elements and the backlight structures. The backlight structures may be formed from optical fiber, a two-dimensional array of light-emitting diodes, a light guide plate that includes a rectangular recess for receiving optical films, or light guide plate structures that include internal light scattering structures. A light guide plate may be provided with alignment features that mate with alignment features on optical films.
