DISPLAY APPARATUS AND OPTICAL AXIS ADJUSTMENT METHOD THEREOF

摘要

A display apparatus includes a liquid crystal panel and a backlight unit that emits light toward the back surface of the liquid crystal panel. The backlight unit includes: an LED; a wiring substrate having the LED mounted thereon; a light guide plate which light from the LED enters through a side surface and exits through a main surface toward the back surface of the liquid crystal panel; and a support component including a first support member that supports the LED and a second support member that supports the light guide plate. The support component is able to move between a first position at which the first support member supports the LED and the second support member supports the light guide plate and a second position at which the first support member is apart from the LED and the second support member supports the light guide plate.

1. A display apparatus comprising:
a display panel; and a backlight unit that emits light toward a back surface of the display panel, wherein the backlight unit includes: a light source that generates the light; a wiring substrate having the light source mounted thereon; a light guide plate including a side surface through which the light generated by the light source enters and a main surface through which the light entering through the side surface exits toward the back surface of the display panel; and a support component including a first support member that supports the light source to position an optical axis of the light source and a second support member that supports the light guide plate to position an optical axis of the light guide plate, and the support component is able to move between (i) a first position at which the first support member supports the light source and the second support member supports the light guide plate and (ii) a second position at which the first support member is apart from the light source and the second support member supports the light guide plate.
