Abstract
A light guide plate includes a through hole; at least one light transmitting component disposed within the light guide plate; at least one light incident surface; at least one light source; and at least one lens structure located between the light source and the incident surface. The light transmitting component is configured to transmit a portion of light that enters the light incident surface to a first region of the light guide plate that would otherwise be masked by the through hole. The light guide plate might backlight a display panel. A method for manufacturing the light guide plate is also provided.
