Backlight unit arranged in a grid structure and display device having the same

A display device comprising:

• a display panel configured to display an image;
• and
• a backlight unit configured to provide light for displaying the image to the display panel,
• wherein the backlight unit comprises:
• a light emitting array including a plurality of light sources configured to emit light, and a printed circuit board on which the light sources are arranged;
• a light guide film configured to guide light emitted from the light sources to the display panel;
• and
• a color conversion layer configured to convert light that has passed through the light guide film into light of a specific color;
• wherein the light sources comprise a plurality of first light sources arranged on a first row of the printed circuit board, and a plurality of second light sources arranged on a second row of the printed circuit board,
• wherein the first light sources are spaced apart from each other by a predetermined distance in every other column of a grid pattern having a column width of the predetermined distance, and the second light sources are spaced apart from each other by the predetermined distance in alternating columns of the grid pattern with respect to the first light sources,
• wherein the light sources comprise a plurality of light emitting areas, each of the plurality of light emitting areas including at least one of the first light sources on a first column of the grid pattern that is electrically connected in series to at least one of the second light sources on a second column of the grid pattern different from the first column, and
• wherein each of the plurality of light emitting areas has a distinct power source.
