Title (EN) PLANAR LIGHT SOURCE DEVICE AND DISPLAY DEVICE
(FR) DISPOSITIF DE SOURCE DE LUMIÈRE PLANE ET DISPOSITIF D'AFFICHAGE

Abstract:
(EN) A planar light source device having a plurality of light emission devices arranged such that the center-to-center distance in the x-direction is Px and the center-to-center distance in the y-direction is Py, and a light diffusion plate disposed on the plurality of light emission devices. For each of the light emission devices, the light beam from among light beams satisfying θ3/θ1 < 1 that has the smallest emission angle θ1xmin satisfies the relationship Ax < Px, where Ax is the distance from the center axis of the point on the light diffusion plate that is reached by the light beam emitted at the emission angle θ1xmin, which is greater than Px/2. The light beam from among light beams satisfying θ3/θ1 < 1 that has the smallest emission angle θ1ymin satisfies the relationship Ay < Py, where Ay is the distance from the center axis of the point on the light diffusion plate that is reached by the light beam emitted at the emission angle θ1ymin, which is greater than Py/2.
(FR) L'invention concerne un dispositif de source de lumière plane ayant une pluralité de dispositifs d'émission de lumière agencés de telle sorte que la distance centre à centre dans la direction x est Px et que la distance centre à centre dans la direction y est Py, et une plaque de diffusion de lumière disposée sur la pluralité de dispositifs d'émission de lumière. Pour chacun des dispositifs d'émission de lumière, le faisceau de lumière parmi les faisceaux de lumière satisfaisant θ3/θ1 < 1 qui a l'angle d'émission le plus petit θ1xmin satisfait la relation Ax < Px, où Ax est la distance de l'axe central du point sur la plaque de diffusion de lumière qui est atteint par le faisceau lumineux émis à l'angle d'émission θ1xmin, qui est supérieur à Px/2. Le faisceau de lumière parmi les faisceaux de lumière satisfaisant theta θ3/θ1 < 1 qui a l'angle d'émission le plus petit θ1ymin satisfait la relation Ay < Py, où Ay est la distance de l'axe central du point sur la plaque de diffusion de lumière qui est atteint par le faisceau de lumière émis à l'angle d'émission θ1ymin, qui est supérieur à Py/2.
(JA) 面光源装置は、X方向の中心間距離がPx、かつY方向の中心間距離がPyとなるように、配列された複数の発光装置と、複数の発光装置の上に配置された光拡散板とを有する。各発光装置について、θ3/θ1<1を満たす光線のうち、最小の発光角度θ1xminの光線は、Px/2<発光角度θ1xminで出射された光線の光拡散板上の到達点の中心軸からの距離Ax<Pxを満たす。θ3/θ1<1を満たす光線のうち、最小の発光角度θ1yminの光線は、Py/2<発光角度θ1yminで出射された光線の光拡散板上の到達点の中心軸からの距離Ay<Pyを満たす。
