The invention relates to the technical field of head-up display, in particular to a light guide plate and a head-up display device. The light guide plate at least comprises a substrate and a light blocking layer, and the light blocking layer at least comprises a shielding layer and a first extinction layer. The first matting layer is configured to comprise the first black ink and the first matting agent, and the weight M1 of the first black ink and the weight N1 of the first matting agent are configured to meet the condition that N1/M1 is larger than or equal to 0.4 and smaller than or equal to 0.8, so that stray light can be eliminated, and meanwhile certain abrasion resistance and adhesiveness are achieved. Meanwhile, by arranging the shielding layer in a matched mode, the light shielding capacity can be improved, the light penetration rate can be reduced, and the extinction effect is further improved. Therefore, the use performance can be improved while the display effect is improved.

    本申请涉及抬头显示技术领域,特别是涉及导光板及抬头显示装置。导光板至少包括基板和阻光层,阻光层至少包括遮蔽层和第一消光层。通过将第一消光层配置为包括第一黑油墨和第一消光剂,并将第一黑油墨的重量M1和第一消光剂的重量N1配置为满足条件:0.4≤N1/M1≤0.8,进而使得能够在消除杂散光的同时具有一定的耐磨性和附着性。同时,通过配合设置遮蔽层,能够提高光线遮蔽能力,降低光线穿透率,进一步提高了消光效果。由此,可以在提高显示效果的同时提高使用性能。
