Backlight unit and display device
First Claim
1. A light generating device comprising:
- an array of light source devices disposed on a substrate and including first and second light source devices forming a first line, the first and second light source devices spaced apart from each other with a first distance and configured to emit light in a first direction;
another array of light source devices disposed on the substrate and including a third light source device forming a second line, the third light source device configured to emit light in a second direction which is different from the first direction,the second line being spaced apart from the first line so that the first light source device is spaced apart from the third light source device with a second distance therebetween,the second distance being equal to or greater than the first distance; and
a reflection layer configured to reflect the light emitted from the first and second light source devices,wherein a light emitting part of the second light source device and a light emitting part of the third light source device are positioned on a same vertical line that is perpendicular to the first direction.

Abstract
A backlight unit and display device are discussed. According to an embodiment, a light generating device includes an array of light source devices disposed on a substrate and including first and second light source devices forming a first line, the first and second light source devices spaced apart from each other with a first distance and configured to emit light in a first direction; another array of light source devices disposed on the substrate and including third and fourth light source devices forming a second line, the third and fourth light source devices spaced apart from each other with a third distance and configured to emit light in a second direction which is different from the first direction, the second line being spaced apart from the first line so that the first light source device is spaced apart from the third light source device with a second distance therebetween.
