Title:
Display device
Document Type and Number:
Japanese Patent JP6015722
Kind Code:
B2
Abstract:
A display device is provided with a light source (82) for radiating light, a display member (30, 230, 430, 630, 730), and a projection member (60, 660, 760). In the display member, a plurality of reflection surface parts (34, 234, 434) having aligned extension directions have display surfaces (30a, 230a, 430a, 630a, 730a) aligned in a specific direction (RD) that is perpendicular to the extension direction (CD) of the reflection surface parts. The projection member has a plurality of emission surfaces (63, 663, 763) that are aligned in the extension direction with spaces therebetween and emit light from the light source toward the reflection surface parts. A linearly extending light image (10, 610, 710) is projected onto the display surfaces by the light emitted along a specific direction by each of the emission surfaces. Each reflection surface part is concavely curved in a direction of withdrawal from each emission surface, and the curvature (1/R )of the curve of each reflection surface part increases as the reflection surface part withdraws from each emission surface along the specific direction.
