A display apparatus (100) comprising a display screen (110) and a backlight assembly (120) is provided. The back-light assembly (120) comprises a distributed light source (122, 124) and a light guide plate (126) having at least two lateral edges. The light guide plate (126) and the distributed light source (122, 124) are arranged such that the light emitted by the distributed light source (122, 124) is edge-coupled into the light guide plate (126) for being forward projected onto the display screen (110) to illuminate the display screen (110) from back. The distributed light source (122, 124) is mounted on a heat sink structure (130). The heat sink structure (130) comprises a plurality of spaced-apart heat dissipating plates (136). Each heat dissipating plate (136) functions as a heat dissipation fin, is in thermal communication with the distributed light source (122, 124) and spans between the two lateral edges of the light guide plate (126).
