摘要： A sheet and a light emitting device are provided which also emit light having an incident angle larger than or equal to a critical angle to significantly increase light extraction efficiency, prevent ambient light reflection, and suppress the occurrence of a distribution of light intensity varying depending on the direction and an imbalance in color. The light emitting device has a surface structure (13) in a surface adjacent to a light emitting element of a transparent substrate (5). The surface of the transparent substrate (5) is virtually divided into minute regions without a gap, the diameter of a largest circle inscribed in the minute region being 0.2 μm or more and 1.5 μm or less. Each minute region has a convex or concave shape in the surface of the transparent substrate 5. The proportions of the convex shapes and the concave shapes are P and 1−P, respectively, where P is within the range of 0.4 to 0.98.

摘要： When first-order diffracted beams leak into a region, which is for receiving only a zeroth-order diffracted beam from an optical disc, due to positional displacement between an objective lens and a hologram element, an offset compensation signal includes an AC component, the offset compensation signal preferably including a DC component only. Accordingly, there may be caused deterioration in a modulation degree of the tracking error (TE) signal. A partial light shielding element 110 is formed on a hologram surface 112a along boundaries between a light receiving region (121a), which receives a zeroth-order diffracted beam, and light receiving regions (121b, 121c), which receive the zeroth-order diffracted beam and first-order diffracted beams, so as to cover the light receiving region (121a). Further, the partial light shielding element 110 shifts phases of transmitted light beams by π, whereby the TE signal is offset-compensated, and the modulation degree can be improved.

摘要： A focus error signal is generated by a first-order diffracted light diffracted by regions 23b, 24b on a hologram plane 2a, and an offset of a tracking error signal is canceled by first-order diffracted light diffracted by regions 21a, 22a, 23a, 24a on the hologram plane 2a. Consequently, even when there is an error in the substrate thicknesses of optical discs, jitter of a reproduction signal at a focus control point can be reduced by decreasing the distance between the focus control point and the point where the jitter is minimized.
