| description | An LED assembly according to an embodiment of the present invention may improve dark regions generated between LED chips by employing a first reflective layer between the LED chips. By employing a transparent optical layer or an optical layer including a scattering particle between an LED chip and a phosphor layer, direct contact between the LED chip and the phosphor layer may be avoided, thereby preventing a low light extraction efficiency. Further, by employing a second reflection layer on side surfaces of an to LED chip, an optical layer, and a phosphor layer, a relatively high contrast may be obtained. An LED assembly may enhance contrast through a reflective layer while increasing light extraction efficiency by including a scattering particle in a phosphor layer. |
