		| Abstract: | We compiled a sample of 54 Seyfert 2 galaxies with both spectropolarimetric and X-ray observations to investigate the role of nuclear obscuration in the visibility of polarized broad emission lines (PBL). We find that at L[O III] > 1041 ergs s−1, Seyfert 2 galaxies without PBL are more obscured in X-ray (at a confidence level of 99%). Our results explain the non-detections of PBL under the framework of the unified model, and put strong constraint on the geometry of the obscuring torus and the scattering region. |
